   Area of a circle can be calculated by using the formulas: Area = π × r 2, where 'r' is the radius. Area = (π/4) × d 2, where 'd' is the diameter. Area = C 2 /4π, where 'C' is the circumference (sometimes referred to as perimeter). Examples using Area of Circle Formula. Let us consider the following illustrations based on the area of circle ...

   How to Calculate the Area. The area of a circle is: π(Pi) times the Radius squared:A = πr2. 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= πr2. = π× 32. = 3.14159... × (3 × 3) = 28.27 m2(to 2 decimal places)
