WebCalculate the circumference and radius of the circle formed. Solution. The circumference of the circle formed = the perimeter of the rectangular wire. Perimeter of a rectangle = 2(L + W) = 2(100 + 50) cm = 2 * 150 cm = 300 cm. Therefore, the circumference of the circle will be 300 cm. Now calculate its radius. Circumference = … WebIf we need an approximate decimal result, we can use π ≈ 3.14. The Area of a Circle.
