Area of Semicircle = 1/2 (π r2)
Step-by-step 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:
Area of the semicircle = 1.57 square feet
radio = 2/2 = 1 ft.
[tex]A_{s} =\frac{\pi r^{2} }{2} =\frac{\pi (1)^{2} }{2} =\frac{\pi }{2}[/tex]
[tex]A_{s} =1.57sq.ft[/tex]
Hope this helps
