If you know the circumference (say 20pi), you can find the radius, because every circumference is just the radius times 2 times pi. We can work backwards and divide 20 pi by pi, to get 20, then divide that by 2 to get the radius of 10. You can find any area if you have the radius, because all areas of circles are pi times the radius squared. If our radius is 10, then 10x10 is 100, and times that by pi to get the area of 100 pi (or about 314 units squared).
