Question

Earths equator is a circle with a radius of 6378km. Finds Earths circumference

Answer 1

Given:

Earth's equator is a circle with a radius of 6378km.

We will find the circumference using the following formula:

`circumference=2\pi r`

Substitute r = 6378 km, and π = 3.14

`circumference=2*3.14*6378=40,053.84`

So, the answer will be circumference = 40,053.84 km
