What is the formula to find the diameter of a circle when the area is known?

If: pi*radius2 = area Then: radius = square root of (area/pi) And: diameter = 2*radius

Square foot of a circle?

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.

How can you calculate the surface area of a diameter?

You didn't specify what figure you are talking about. Assuming a circle: divide the diameter by 2 to get the radius. Then use the well-known formula area = pi x radius2.You didn't specify what figure you are talking about. Assuming a circle: divide the diameter by 2 to get the radius.

How do you work out the area of a circle in a square?

The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2.
