Since the area of a circle is pi times the radius squared. The radius is 7. The diameter would be 14.

If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
Using 3.14 as Pi the area of circle is: 530.66
Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).
Diameter = 1/2 of the circle's radius. Diameter = 2 times the square root of (the circle's area/pi) Diameter = the circle's circumference/pi
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
