    Circumference of a circle with radius 8 =

    c = 2 pi 8

    For semi circle we will divide this by 2 and then add the base segment which is the length of the radius * 2.

    p = (2 * 3.14 * 8) / 2 + 16

    perimeter = 41.12 m

    Hello:

    the perimeter of a circle is : P=2πr r : radius r = 8m

    P = 2*3.14*8 = 50.24

    the approximate perimeter of a semi circle with a radius of 8 m is : P/2 = 25.12m
