- A golf ball has a diameter of 3cm and a dimple has a diameter of 0.3cm. Give a (reasonable) estimate for the largest number of dimples that can fit on the golf ball. Hint: The number of dimples is lower than 100.
Area of the ball = 4*pi*R^2
The area of a dimple is the area of a spherical cap.
The approximate number of dimples is 1/(1-√(1-r^2/R^2))
