<u>We are given</u>
- Radius of Earth; 6.4 x 100 meters = 640 meters
Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

When we substitute the radius in the formula, we get;


Take π as 3.14


Simplify the numerator;


Divide the numerator by 3;
