The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.

The area of a circle is calculated from the formula Pi x r2 . A 1cm diameter circle has a radius of 0.5cm, thus it has an area of 0.785cm2

The area of a circle is πr^2 where r is the radius and in terms of diameter it is πD where D is your diameter.

Area = Pi(d/2)2 where d = diameter

The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.

To calculate this you will need the diameter of the circle. The formula is: diameter/2*pi If you don't know the diameter you can also use the area of the circle: Sqrt(Area/pi) = radius

If Area of a circle = (2)(pi)(r), and diameter = 2r, then: diameter = 2r = Area of circle / pi, where pi = 3.14

Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle.

Divide the diameter by 2, to get the radius. Then you can use the standard formula for the area of a circle.

The area of a circle is πr^2 where r is the radius and in terms of diameter it is πD where D is your diameter.

Circumference of a circle is (pi * diameter). Area of a circle is (pi * r2).

D=Diameter, pi=3.14159... Area of circle = (D/2)2 * pi

Area = Pi(d/2)2 where d = diameter

Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle (area = pi x radius2).
