What is the approximate perimeter of a semicircle with a radius of 6 cm?

use pi star times = 3.14.
express your final answer to the nearest hundredth.

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.
