Perimeter of circle to radius

WebAn online calculator to calculate the area A and perimeter P of a circle given its radius r. The formulas for the perimeter P and area A of a circle are given by: P = 2 π r A = π r 2. WebPerimeter of a circle = 2πr where r = radius, and π = 22/7 or 3.14 approx: Difference Between Perimeter and Area. The area is the space occupied or enclosed by a closed shape whereas the perimeter is the total distance covered around the edge of the shape. We define the area as the amount of space covered by a flat surface of a particular shape.
