Hello @supercait10 !
I saw your post on Twitter, so I came by to try to help :)

The Equation for the Circumference of a Circle is   2 * n * (Radius)

n = 3.14
(Radius) = 3.7

and we can just plug this into that equation :)

Circumference of this Circle = 2 * (3.14) * (3.7) = [answer]

I hope this helped! :) tag me if you need me to help clarify anything on this question ^_^
