Question

Ariel is filling a giant beach ball with air. The radius of the beach ball is 30 cm.

What is the volume of air that the beach ball will hold?
Either enter an exact answer in terms of π or use 3.14 for π

Answer 1

In order to solve this problem, we need to know the volume of a sphere.

The volume of a sphere is (4/3)pir^3

In this case our r value, or radius, is 30cm.

If we plug in 30cm to the equation like so:

(4/3)pi(30)^3

The answer is 113097 cm^3 of air
