Why do golf balls have dimples?
Dimples on a golf ball create a thin turbulent boundary layer of air that clings to the ball's surface. This allows the smoothly flowing air to follow the ball's surface a little farther around the back side of the ball, thereby decreasing the size of the wake.

How do you find the radius?
How do you find the radius of a circle?
- Radius of a circle from area: if you know the area A , the radius is r = √(A / π) .
- Radius of a circle from circumference: if you know the circumference c , the radius is r = c / (2 * π) .
- Radius of a circle from diameter: if you know the diameter d , the radius is r = d / 2 .
How do you find the diameter of a sphere without the radius?
