What is the formula for perimeter of a semicircle?
Perimeter of a Semicircle
The formula for a circle’s circumference, C, is C = 2 * pi * r, where r is, again, the circle’s radius.
A semicircle is half a circle, however, so we’ll need to divide the formula for perimeter by two just like we did the formula for area.
The perimeter P = pi * r.
