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
