Question

The earth has a diameter of 7926.41 miles.what is the cicumfernece of the earth?

Answer 1

You would turn the diameter into a radius so that you can put it into the Circumference formula. Doing so would get you 3963.205.

Then, you would put that into the formula C=$2 \pi r$

C= 3963.205

Hope this helped :)

Answer 2

What u do is c equals pi multiples by Diameter
