Question

Carlos went to PetSmart to get his hamster an exercise ball. There was a small one with a 5 inch diameter and a 13 inch ball. How much more space (volume) is in the larger than the smaller? Round to the nearest tenth. (PLEASE ANSWER ASAP)

Answer 1

Vol of small ball = 4/3 pi (2.5)^3
Vol of larger on = 4/3 pi (6.5)^3
Difference = 4//3pi(6.5^3-2.5^3)
= 4/3 pi (259)
= 1085.0
