Before you can calculate the circumference of the circle, you need to know the radius. To get the radius, use the area of a circle formula: A=πr2.

Using A=πr2, substitute the area for A and solve for r.

Once you have r, use the circumference of a circle formula: C=2πr

Substitute the radius you calculated into that formula to get the circumference!
