Question

Area of This Semi Circle

Answer 1

Answer:

Area of Semi Circle

The area of a semicircle is half of the area of the circle. As the area of a circle is πr2. So, the area of a semicircle is 1/2(πr2 ), where r is the radius. The value of π is 3.14 or 22/7

Answer 2

It's diameter is 14 CM so first we will find the area of full circle then divide it by 2

so,

area of circle = pi*r^2

r = 14/2 =7

3.14*7*7= 153.86cm^2

semi circle = 153.86/2 cm2
