Perimeter and area of semicircle

WebArea of Semicircle Formula. A semicircle has half the surface area of a circle. Because the radius of a circle is πr 2, so a semicircle’s area is 1/2(πr 2), wherein r is the radius and the value of π = 3.14 or 22/7. Perimeter of Semicircle Formula. A semicircle’s perimeter is equal to half of the circle’s circumference plus its diameter. WebOK, the area of a circle with diameter "D" is: Area of Circle = 1 4 π D 2. So the area of a semicircle is half of that: Area of Semicircle = 1 8 π D 2. And so the area of each semicircle is: A = 1 8 π a 2. B = 1 8 π b 2. C = 1 8 π c 2. Now our question:
