Question

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. What is the approximate volume of glass used to make the ball? Use 3.14 to approximate pi. a 113.0 cm³ b 523.3 cm³ c 1620.2 cm³ d 2143.6 cm³

Answer 1

The Correct Answer is 523.3 cm^3

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

Answer 2

1620.2

Sorry if I'm late The correct answer is 1620.2

Have a good day!
