I think you mean circumference...Area is

. We have the area so we need to use it to solve for the radius which we will then use in the circumference formula.

. Divide both sides by pi to get

. Of course the simplification of the left side gives us

and r = 4. Now fill that in to the circumference formula, which is

, to get C

which is a circumference of
You can solve an easy equation in your head by using the multiplication table.
