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
