Value of pi = 3.14 Radius of the semicircle = 6 cm Diameter of the semicircle = 6 * 2 cm = 12 cm Perimeter of a semicircle = pi * Diameter *(1/2) = 3.14 * 12 * 1/2 = 3.14 * 6 = 18.84 cm From the above deduction, we can conclude that the perimeter of the semicircle in question is 18.84 cm. I hope that this is the answer that has come to your desired help.
