Answer 3

Yup, it gives me an explanation. Here:

Use the formula below to find the volume of the beach ball. Remember that the radius is one-half of the diameter.

V=3/4 pi r^3
=4/3(3.14)(9 in)^3
=3,052.08

Therefore, the beach ball has a volume of 3,052.08 cubic inches when it is completely full.
