Question

A ball has a diameter of 6 inches. A smaller ball has a radius of 2 inches. What is the approximate difference between the volume of the two balls

Answer 1

The difference between the volumes is 79.55 cubic inches.

What is the difference between the volumes?

The volume of a sphere of radius R is:

$V = (4/3)*3.14*R^3$

Here we have two spheres, the larger has a diameter of 6 inches, so its radius is:

R = 6in/2 = 3in

The smaller ball has a radius of 2 in.

Then the difference between the volumes is:

$V = (4/3)*3.14*( (3in)^3 - (2in)^3) = 79.55 in^3$
