How do you find the surface area of a golf ball?
Here, we have given some parameters we will use them to find out the total surface area of that golf ball by using the formula: Surface area of a sphere = $4\pi {r^2}$. And then we will remove the area of each dimplet from the total surface area. Radius of each dimplet = $2mm = \dfrac{2}{{10}}cm$.

1.680 inchesGolf Ball Size: According to the USGA Rules of Golf, the diameter of the ball shall not be less than 1.680 inches (42.67 mm). A smaller golf ball will generally fly further than a larger one given the weight is equal.
What is the surface of a golf ball made of?
The exterior surface of the golf ball is referred to as its cover and is constructed either of Surlyn (a thin, plastic resin created and trademarked by DuPont) or urethane (a slightly softer, slightly less durable synthetic compound). All else being equal, Surlyn can contribute to distance, but tends to inhibit spin.

How big is a golf ball?
The Rules of Golf, jointly governed by the R&A and the USGA, state in Appendix III that the diameter of a "conforming" golf ball cannot be any smaller than 1.680 inches (42.67 mm), and the weight of the ball may not exceed 1.620 ounces (45.93 g). The ball must also have the basic properties of a spherically symmetrical ball, generally meaning that the ball itself must be spherical and must have a symmetrical arrangement of dimples on its surface. Additional rules direct players and manufacturers to other technical documents published by the R&A and USGA with additional restrictions, such as radius and depth of dimples, maximum launch speed from test apparatus (generally defining the coefficient of restitution) and maximum total distance when launched from the test equipment.
How does impact affect golf ball?
When a golf ball is hit, the impact, which lasts less than a millisecond, determines the ball's velocity, launch angle and spin rate, all of which influence its trajectory and its behavior when it hits the ground.
Who broke the world record for the fastest golf ball?
Canadian long drive champion Jason Zuback broke the world ball speed record on an episode of Sport Science with a golf ball speed of 328 km/h (204 mph). The previous record of 302 km/h (188 mph) was held by José Ramón Areitio, a Jai Alai player.
How big is a golf ball?
Depending on which side of the Atlantic you live (there is a difference between an American ball and a British ball), the diameter of a golf ball is between 41.1mm and 42.6mm. There are no regulations about how many dimples a golf ball has to have. Different manufacturers have different designs, and patterns between 300 ...
Why are golf balls covered by dimples?
This is for aerodynamic reasons. The dimples encourage the air moving over the ball to transition from laminar boundary layer to turbulent flow a little sooner.
How many mm are dimples in a golf ball?

What does it mean when a golf ball has a dimple?
This will mean they have a higher surface area than the cap they are replacing. The more dimples, the higher the surface area of the ball.
What does a dimple do to a sphere?
The dimples will reduce the volume of the sphere (they all press in). The surface area will could decrease, stay the same, or increase, depending on the geometry of the depressions.

Who hit golf balls on the moon?
In 1971, astronaut Alan Sheppard hit a couple of golf balls on the moon after landing there on Apollo 14. With pretty much no air resisitance, and significantly lower gravity, there is potential for them to have travelled a long, long, way.

Sketchy Putts
As we wrote about in a recent article that was based off a 2012 study, low-skilled putters tend to shift their focus around rapidly while they stand over their putts, keying-in on a number of different spots on and around the golf ball.
Fat Shots
As reported in a 2005 issue of GOLF Magazine, sometimes a change in perspective is all it takes to fix a fault…
Slices
Hitting a slice? You’re likely swinging too far out-to-in with an open clubface. To fix it, try swinging more in-to-out by aiming for a spot on the inside the golf ball and hitting that.
Hooks
And finally, the opposite of that is true, too. If you’re swinging too far from in-to-out with a closed clubface, resulting in some nasty hooks, look at a spot on the outside of the golf ball and try hitting that.
Why do you need a rough face on a golf ball?
A rough club face will help put more backspin on the ball. The amount of spin you place on a golf ball directly affects the success or failure of a variety of shots. For example, you must impart just the right amount of side spin on the ball to hit a controlled fade or draw.
How much roughness is allowed on a club head?
Club faces conforming to USGA regulations may not have a roughness measured at more than 180 micro inches.
Is a dimpled golf ball smooth?
A dimpled golf ball is, obviously, not a completely smooth surface. Additionally, the club’s grooves are designed to apply friction to slow the ball’s progress up the club face. This results in a greater amount of backspin. Likewise, a club head designed with a rough face adds even more friction, which further resists the ball’s ability ...
Overview
Aerodynamics
When a golf ball is hit, the impact, which lasts less than a millisecond, determines the ball's velocity, launch angle and spin rate, all of which influence its trajectory and its behavior when it hits the ground.
A ball moving through air experiences two major aerodynamic forces, lift and drag. Dimpled balls fly farther than non-dimpled balls due to the combination of these two effects.
History
It is commonly believed that hard wooden, round balls were the first balls used for golf between the 14th through the 17th centuries. Though they were no doubt used for other similar contemporary stick and ball games, made from hardwoods such as beech and box trees, there is no definite evidence that they were used in golf in Scotland. It is equally, if not more likely, that leather balls filled with cows' hair were used, imported from the Netherlands from at least 1486 o…
Regulations
The Rules of Golf, jointly governed by the R&A and the USGA, state in Appendix III that the diameter of a "conforming" golf ball cannot be any smaller than 1.680 inches (42.67 mm), and the weight of the ball may not exceed 1.620 ounces (45.93 g). The ball must also have the basic properties of a spherically symmetrical ball, generally meaning that the ball itself must be spherical and must have a symmetrical arrangement of dimples on its surface. While the ball's dimples must be sy…
Design
Dimples first became a feature of golf balls when English engineer and manufacturer William Taylor, co-founder of the Taylor-Hobson company, registered a patent for a dimple design in 1905. William Taylor had realized that golf players were trying to make irregularities on their balls, noticing that used balls were going further than new ones. Hence he decided to make systematic tests to determine what surface formation would give the best flight. He then developed a patter…
Behavior
Today, golf balls are manufactured using a variety of different materials, offering a range of playing characteristics to suit the player's abilities and desired flight and landing behaviours.
A key consideration is "compression", typically determined by the hardness of the ball's core layers. A harder "high-compression" ball will fly further because of the more efficient transfer of energy into the ball, but will also transmit more of a shock through the club to the player's hands …
Selection
There are many types of golf balls on the market, and customers often face a difficult decision. Golf balls are divided into two categories: recreational and advanced balls. Recreational balls are oriented toward the ordinary golfer, who generally have low swing speeds (80 miles per hour (130 km/h) or lower) and lose golf balls on the course easily. These balls are made of two layers, with the cover firmer than the core. Their low compression and side spin reduction characteristics su…
Marking and personalization
Golfers need to distinguish their ball from other players' to ensure that they do not play the wrong ball. This is often done by making a mark on the ball using a permanent marker pen such as a Sharpie. A wide number of markings are used; a majority of players either simply write their initial in a particular color, or color in a particular arrangement of the dimples on the ball. Many players make multiple markings so that at least one can be seen without having to lift the ball. Marking t…
