Find the volume of the earth if the diameter is 7917.5 miles.

The volume of Earth is .

To solve, you must remember that to find the area of a circle, (includes volume since circle volume and area is same) you must do A=πr².

So, A=π3958.75²

How did we get 3958.75? Well, to find the area, you must multiply r by r (radius).

So, 3958.75² is 15671701.5625.

15671701.5625π

step-by-step explanation:

(s)he  is right it would be 5.5% because it is smaller than 15.5% or anything smaller than 15.5% in general
