<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.
![\implies \text{Volume of sphere =} \ \dfrac{4\pi r^{3}}{3}](https://tex.z-dn.net/?f=%5Cimplies%20%5Ctext%7BVolume%20of%20sphere%20%3D%7D%20%5C%20%20%20%5Cdfrac%7B4%5Cpi%20r%5E%7B3%7D%7D%7B3%7D)
When we substitute the radius in the formula, we get;
![\implies\text{Volume of sphere} = \dfrac{4\pi (640)^{3}}{3}](https://tex.z-dn.net/?f=%5Cimplies%5Ctext%7BVolume%20of%20sphere%7D%20%3D%20%5Cdfrac%7B4%5Cpi%20%28640%29%5E%7B3%7D%7D%7B3%7D)
![\implies\text{Volume of sphere} = \dfrac{4\pi (640)(640)(640)}{3}](https://tex.z-dn.net/?f=%5Cimplies%5Ctext%7BVolume%20of%20sphere%7D%20%3D%20%5Cdfrac%7B4%5Cpi%20%28640%29%28640%29%28640%29%7D%7B3%7D)
Take π as 3.14
![\implies\text{Volume of sphere} = \dfrac{4\pi (640)(640)(640)}{3}](https://tex.z-dn.net/?f=%5Cimplies%5Ctext%7BVolume%20of%20sphere%7D%20%3D%20%5Cdfrac%7B4%5Cpi%20%28640%29%28640%29%28640%29%7D%7B3%7D)
![\implies \text{Volume of sphere} = \dfrac{4(3.14)(640)(640)(640)}{3}](https://tex.z-dn.net/?f=%5Cimplies%20%5Ctext%7BVolume%20of%20sphere%7D%20%3D%20%5Cdfrac%7B4%283.14%29%28640%29%28640%29%28640%29%7D%7B3%7D)
Simplify the numerator;
![\implies \text{Volume of sphere} = \dfrac{4(3.14)(640)(640)(640)}{3}](https://tex.z-dn.net/?f=%5Cimplies%20%5Ctext%7BVolume%20of%20sphere%7D%20%3D%20%5Cdfrac%7B4%283.14%29%28640%29%28640%29%28640%29%7D%7B3%7D)
![\implies \text{Volume of sphere} = \dfrac{3292528640}{3}](https://tex.z-dn.net/?f=%5Cimplies%20%5Ctext%7BVolume%20of%20sphere%7D%20%3D%20%5Cdfrac%7B3292528640%7D%7B3%7D)
Divide the numerator by 3;
![\implies \text{Volume of sphere} = \dfrac{3292528640}{3}](https://tex.z-dn.net/?f=%5Cimplies%20%5Ctext%7BVolume%20of%20sphere%7D%20%3D%20%5Cdfrac%7B3292528640%7D%7B3%7D)
![\implies \text{Volume of sphere} = \boxed{1097509546.67 \ \text{m}^{3} } \ \ \ (\text{Estimated})](https://tex.z-dn.net/?f=%5Cimplies%20%5Ctext%7BVolume%20of%20sphere%7D%20%3D%20%5Cboxed%7B1097509546.67%20%5C%20%5Ctext%7Bm%7D%5E%7B3%7D%20%7D%20%5C%20%5C%20%5C%20%28%5Ctext%7BEstimated%7D%29)
