WebPerimeter of a circle = 2πr units Where, 'r' is the radius of the circle and π (Pi) is the mathematical constant with an approximate value of 3.14. Solved Example: Find the area and perimeter of a circle, if the radius is 5 units. Solution: Given: Radius (r) = 5 units Area of a circle = πr 2 = 3.14 × 5 2 = 3.14 × 25 = 78.5 square units WebMultiplying both sides of the formula by d d gives us C = \redD\pi d C = πd which lets us find the circumference C C of any circle as long as we know the diameter d d. Using the formula C = \pi d C = π d Let's find the circumference of the following circle: 10 10 The diameter is 10 10, so we can plug d = 10 d = 10 into the formula C = \pi d C = πd:
