How do you find the diameter of a circle if you have the area?

The formula A = (pi) r2 lets you find the radius, which is half of the diameter. Divide the area by pi, then take the square root of that value, which is the radius. Then multiply by 2 to get the diameter. -- Example: Area = 100 A = (pi) r2 100 = (3.1416) r2 r2 is 100/3.1416 or about 31.83, and the square root is 5.64 r = 5.64 and D = 11.28

What is the area of a circle with a diameter of 100 feet?

7850 sq ft. Formula is pi x R squared. Diameter of 100 means Radius (r) is 50. 50 squared (multiplied by itself) is 25000. Multiply THAT by the value of pi- or 3.14, and you get 7850 sq ft.


What is the area of a circle with a diameter of 20 meters?

Diameter is 20 meters, hence radius is 10 meters. Area of circle = pi * r * r = 3.1415 * 10 * 10 = 3.1415 * 100 = 314.15 square meters
