To find the area of a circle, certain data should be given. Usually, it is the radius that is given or diameter to find the area of a circle. If the given is in radius, multiply the value of π by the square of radius(r²) or it can be written as A = π r². If the given is in diameter, convert first the diameter into radius. Since diameter is 2r or radius plus radius, divide the diameter by 2 to convert it into radius. Then, square the radius and multiply it to the value of pi; where radius squared is represented by r² and pi is represented by π to get the area of a circle.
