- Radius of a Circle
The area of a circle is the region occupied by the circle within its boundary (circumference) in a 2D plane. If the radius of a circle is r, the area is defined as A = πr 2, where is a mathematical constant with approximate value of 3.14 or 22 7 . Area of a circle is measured in square units .

The area of a regular polygon is half its perimeter multiplied by the distance from its center to its sides, and because the sequence tends to a circle, the corresponding formula–that the area is half the circumference times the radius–namely, A = 1 2 × 2πr × r, holds for a circle.
