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)
6 dni temu · These are the formulas to calculate the circumference and area of a circle: c = 2πr A = πr² = πd²/4. where: c stands for circumference; r for radius; and; d for the diameter of the circle. π is a constant approximately equal to 3.14159265359 and, among other things, represents the circumference-to-diameter ratio of any circle.
