Question

A beach ball has a radius of 12 in.. How much air will the beach ball hold? (leave your answer in terms of π)

Answer 1

This question is asking for the volume of the ball. Remember the formula for the volume of a sphere:
\[V = 4 pi r^{3}/3\]
Since you already have the radius, just plug it in for r.

Answer 2

\[V=\frac{4}{3}\pi r ^{3}=\frac{4}{3}\pi 12^{3}=2304\pi\]cbic inches
