Question

A crystal ball has a radius of 4 inches. What is the approximate volume of the crystal ball? Use 3.14 for mc017-1.jpg. Round to the nearest tenth.

Answer 1

Hi there!

To find the volume of the ball, we should follow this formula: 

4/3*pi*r^3

Since the radius is 4, we can just plug the value in:

4/3*3.14*4^3
= 267.946667

Round to the nearest tenth:
= 267.9

Your answer is 267.9. 

Hope this helps!
