Have a good day!

Answer:

The Correct Answer is 523.3 cm^3

Step-by-step explanation:

A hollow crystal ball is made of glass that is 3 cm thick. The ball has a radius to the OUTSIDE surface of 8 cm, so 8 - 3 = 5.

v = 4/3 pi (5)^3

v = 4/3 pi (125)

v = 523.3333333

The volume of the hollow 3 cm thick crystal ball is approximately 523.3 cm^3
