Question

What is the total surface area of the earth?

Answer 1

509 600 000 square km (197 000 000 square miles). Area of land: 148 326 000 km2 (57 268 900 square miles), this are 29% of the total surface of Planet Earth. Area of water: 361 740 000 km2 (139 668 500 square miles), this are 71% of the total surface of the Earth.

Answer 2

The total surface area of the Earth is approximately 510 million square kilometers.

Step-by-step explanation:

The total surface area of the Earth is approximately 510 million square kilometers.

To calculate this, we can use the formula for the surface area of a sphere:

A = 4πR²

Where A is the surface area and R is the radius of the Earth.

The radius of the Earth is approximately 6,371 kilometers.

Substituting the values into the formula:

A = 4π(6,371)² ≈ 510 million square kilometers.
