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?

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

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##.
