Volume of the beach ball: 4/3*pi*radius^3
In the US, a billiards ball or pool ball is 2.25 inches in diameter. This is 1.125 for its radius. The only exception is the oversize cue ball, which is 2.375 inches in diameter.
10 inches
4.325
The radius is half the diameter of a ball (or sphere), so if diameter is 7.91 units the radius is 3.955 units.

A typical beach ball is about a quarter of a meter in radius. They are not all exactly the same size, so this answer is not precise.
radius of cricket ball is 52 mm. its red in test cricket. has white color in odi.

The radius is half the diameter of a ball (or sphere), so if diameter is 7.91 units the radius is 3.955 units.
Its usually defined by the diameter of the ball, like an 11 inch disco ball would have a diameter of 11 inches, not a radius of 11 inches.
The uncertainty in radius is approx 5.95%.
