Question

Find the area of the semicircle

Answer 1

Area of Semicircle = 1/2 (π r2)

Explanation:

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

Area of the semicircle = 1.57 square feet

Explanation:

radio = 2/2 = 1 ft.

`A_(s) =(\pi r^(2) )/(2) =(\pi (1)^(2) )/(2) =(\pi )/(2)`

`A_(s) =1.57sq.ft`

Hope this helps
