The perimeter of a semicircle formula = (πR + d) or (πR + 2R), or R(π + 2) units. where, R = radius of a semicircle; π(pi) is 22/7 or 3.142 approximately, and, d = Diameter of a semicircle. Circumference of a Semicircle Formula. The
The circumference of a semicircle is not equal to half of the circle circumference - you need to add also the diameter of the semicircle, as another boundary was created: P s e m i c i r c l e = P c i r c l e 2 + 2 ⋅ r
