If: pi*radius2 = area Then: radius = square root of (area/pi) And: diameter = 2*radius
To find the area of a circle, either the diameter or the circumference must be known. The formula for the area from the diameter is (pi)*(1/2 of diameter) squared. From the circumference, simply substitute (circumference / pi) for diameter.
You didn't specify what figure you are talking about. Assuming a circle: divide the diameter by 2 to get the radius.

The formula for the area of a circle is: area = pi x radius2. The radius is half the diameter.
The general formula for the area of a circle is pi times the radius squared. The radius is half the diameter, so the area is pi times half the diameter times half the diameter again.
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.
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
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.
