A beach ball has a radius of 12 in.. How much air will the beach ball hold? (leave your answer in terms of π)
A)
108π in.3
B)
144π in.3
C)
192π in.3
D)
2304π in.3
So we want to know how much air is there in the beach ball with radius r=12 in and we can leave the answer in terms of pi. So to get to the answer we must calculate the volume V of the ball. V=(4/3)r^3*pi. Now we simply plug in the numbers: V=2304*pi so the correct answer is D.
