Let P =the perimeter of semicircle
--
P = Circumference/2 + Diameter
--
You are given: perimeter of semicircle = area of semicircle
---
(multiply both sides by 2)
(divide both sides by r)
(divide both sides by )

The number of centimeters in the perimeter of semicircle is numerically the
same as the number of square centimeters in its area.
so pi*r = pi*r^2/2 (r is the radius of the circle)
so r=2
thus the number of centimeters in the radius of the semicircle=2
