Find exact volume of a sphere with a radius of 10in

To find the volume of a sphere, we can apply the following formula:

(4

/3) πr^3

We know the radius is 10, so we can plug that value in.

(4/3) * pi * 10^3

V = 4188.79020479in^3

The question says "exact" volume, so I've included all of the digits in the tenths and beyond place, without rounding.
