Question

A kickball has a 10 inch diameter. What is the volume of the ball?

Answer 1

A kickball is a sphere, so to solve this, we are going to use the formula for the volume of a sphere: $V= \frac{1}{6} \pi d^3$
where
$V$ is the volume of the sphere.
$d$ is the diameter of the sphere. 

We know form our problem that the diameter of the kickball is 10 inches; since the kickball is a sphere,  $d=10in$. Lets replace that value in our formula to find $V$:
$V= \frac{1}{6} \pi d^3$
$V= \frac{1}{6} \pi (10in)^3$
$V=523.6in^3$

We can conclude that the volume of the kickball is 523.6 cubic inches.
