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. Round to the nearest hundredth if necessary.
____cm^3

Answer 1

Answer:

3037.95 in^3

Step-by-step explanation:

Answer 2

Using 3.14 as an estimate for pi, the answer is 3037.95 in. cubed. But if more digits of pi were used, the answer is 3039.49 in. cubed. I found the answer by using the sphere volume formula (4/3) on both sphere measurements, then subtracted the smaller core sphere from the rest of the sphere. The above named numbers were the result.
