What is the Surface Area of the Earth?

Answer – The surface area of the earth is 511 million square kilometers, or 197 million square miles.

Explanation: 

Like any other spherical object, the surface area of the earth can also be found using the formula A = 4π r2, where r represents radius.

The radius of the earth is 6378 km.

Therefore, its surface area A = 4 × π × (6378)2 = 511,185,932.52 km2 or 511 million km². This is approximately 197 million mi².
