WebFind the perimeter of a circle whose diameter is 14 cm. [Note: Take π = 3.14] Solution: Given, diameter = 14 cm Hence, radius, r = 14/2 = 7 cm As we know, the perimeter of a circle = 2πr units P = 2 (3.14) (7) P = 14 (3.14) P = 43.96 Thus, the perimeter/circumference of the circle = 43.96 cm. 3. WebThe perimeter of a circle = π D Perimeter or circumference = 22/7 × 7 = 22 in Answer: Perimeter of circle or circumference = 22 in. Example 2: Using the perimeter of a circle …
