Question

To the nearest kilometer, how far would you go if you traveled along the circumference of the equator, assuming the equator is a circle with a radius of kilometers?

Answer 1

If one traveled along the circumference of the equator, he will go `40030` `km` - to the nearest kilometer.

Explanation:

Assuming questioner is referring to earth and its known radius is `6371` `km` and that it is a perfect circle at equator with this radius,

As circumference of a circle is given by `2pir`

If one traveled along the circumference of the equator,

he will go `2pixx6371=2xx3.14159xx6371=40030.14` `km` or to the nearest kilometer, it would be `40030` `km`.
