Question

If the radius is 6371, what is the circumference?

Answer 1

The formula to find the circumference is pi*radius^2. Since your radius is 6371, the radius squared is 40589641 and that times pi is 127451473. That is your circumference

Answer 2

In order to find the circumference of a circle, you must use the formula c=2*$\pi$*r. 

Since you're already given the radius, all you have to do is use the formula and do 2 times 3.14 times 6371 and you get 40009.88 as your circumference.
