Perimeter of a Semicircle. The perimeter of any shape is the total length of all its sides. Since a circle has no sides, its perimeter (also known as its circumference) is the length of the circle's exterior. The formula for a circle's circumference, C, is C = 2 * pi * r, where r is, again, the circle's radius this is the answer
That's right but circumference of semi circle is pi*r+2*r
