How to Calculate the Area. The area of a circle is: π ( Pi) times the Radius squared: A = π r2. or, when you know the Diameter: A = (π/4) × D2. or, when you know the Circumference: A = C2 / 4π.
Area of a Circle. Area of a circle is the region occupied by the circle in a two-dimensional plane. It can be determined easily using a formula, A = πr2, (Pi r-squared) where r is the radius of the circle. The unit of area is the square unit, such as m2, cm2, etc.

Formula for Area of circle. The formula to find a circle's area π π ( radius) 2 usually expressed as π ⋅r2 π ⋅ r 2 where r is the radius of a circle . Diagram 1. Area of Circle Concept. The area of a circle is all the space inside a circle's circumference .
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.
