7.6 Surface Area and Volume of Spheres

If the radius of this beach ball is 12 inches across. About how many cubic inches of air can this ball hold?

Formula needed to solve this: V= 4/3 (pi) r³

First, you need to plug in your radius. V= 4/3 (pi) 12³ The equation then should look like this: V= 4/3 (1728)(pi) Now, take 4/3 divided by 1728. =2,304(pi) square inches That should now equal: about 7238.22
