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. Example: What is the area of a circle with radius of 3 m ? Radius = r = 3. Area = π r2. = π × 32. = 3.14159... × (3 × 3) = 28.27 m2 (to 2 decimal places)
The formula to find the area of a circle is to square the radius and multiply by π. The inverse of this is divide the area by π, then square root. 900π ÷ π = 900.
