How do you find the area of a circle with the circumference? - Answers

The area of a circle is (pi x radius squared) A = πr2 The circumference is (pi x diameter) C = π (2r) So if you have the circumference, the area is the circumference squared, divided by 4pi (about 12.566). A = C2/4π Example: A circle with a diameter of 6 inches has a radius of 3 inches Area A = pi (32) or about 28.27 square inches Circumference C = pi (6) or about 18.85 inches Using C2/4pi, the area is 18.85 x 18.85 / 12.566 = about 28.27 square inches
