Question

A spherical water balloon has a diameter of 10 cm. How much water is needed to fill the balloon, in cubic centimeters? Round your answer to the nearest centimeters

Answer 1

You need to find the volume so, $4* \pi *r ^{3} / 3$ = volume. So then we need the radius which would be 5. So, $5* \pi * 5 ^{3} / 3$ = about 523.3 cm cubed
