How Do I Find The Area Of A Circle With A RadiusHow 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) Method 1 Using Radius to Find Area Download Article 1 Identify the radius of a circle The radius is the length from the center of a circle to the edge of the circle You can measure this in any direction and the radius will be the same The radius is also one half of the diameter of a circle

This calculator will calculate the area of a circle given its diameter, using the famous formula area = pi times (d/2) squared. It supports different units such as meters, feet, and inches.

The formula for the area of a circle is π x radius2, but the diameter of the circle is d = 2 x r 2, so another way to write it is π x (diameter / 2)2. Visual on the figure below: π is, of course, the famous mathematical constant, equal to about 3.14159, which was originally defined as the ratio of a circle's circumference to its diameter.
