The area of a circle is calculated as A = πr². This is a great starting point. The full angle is 2π in radians, or 360° in degrees, the latter of which is the more common angle unit. Then, we want to calculate the area of a part of a circle, expressed by the central angle. For angles of 2π (full circle), the area is equal to πr²: 2π → πr²Using Pi We can use π to find a Circumference when we know the Diameter Circumference = π × Diameter Example: You walk around a circle which has a diameter of 100 m, how far have you walked? Distance walked = Circumference = π × 100 m = 314.159... m = 314 m (to the nearest m) Also we can use π to find a Diameter when we know the CircumferenceYou get the area of a circle or a disc by multiplying its radius by the number Pi (π).
