Explanation:
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.
