How do you calculate the volume of a bowling ball using its circumference?

Answer 1

A Bowling ball is a sphere.

The following formulas will help: C = 2*pi*r. r = C/2/pi [C is circumference and r is radius]

Volume = (4/3)* pi * r³ ; substitute C = 2*pi*r into the volume formula:

V = (4/3)*pi*(C/2/pi)³ = (4/3)*pi*(C³)/(2³)/(pi³) = (C³)/(6*pi²).

This is helpful, because it isn't very easy to measure the radius of something like a ball, but it's pretty straightforward to wrap a string around it and get the circumference.
