The Earth

The Earth's surface is 510,000,000 km2. Calculates the radius, equator length, and volume of the Earth, assuming the Earth has the shape of a sphere.

Correct answer:

r =  6370.5973 km
o =  40027.6436 km
V =  1083001548067.1 km3

Step-by-step explanation:

S=510000000 km2 S = 4 π r2  r=4πS=4 3.1416510000000=6370.5973 km
