Question

A non-scale model of the earth has a diameter of 18 in. Within an outer clay layer, there is a core made of a ball with a diameter of 3 in.


What is the volume of the clay?

Use 3.14 to approximate pi and express your answer in hundredths.

Answer 2

I think the answer is 900.13

Answer 3

\[(4/3)\pi(r^3)_{ball} = (4/3)(\pi)(1.5)^{3} = 14.3 cm^{3}_{volume~ball}\]

\[\frac{ 4 }{ 3 }*(9)^{3}*\pi = 3052~inches^{3}\]

\[Volume~model-Volume~ball = 3052-14.3 = 3038inches^{3}\]
