Best answer 2 2 votes Area of semicircle = $\frac{1}{2} \times $ area of circle $= \frac{\pi r^2}{2} $ Diameter $=16$ inches $\implies $ radius $=8$ inches Required Area $=\frac{\pi r^2}{2} = \frac{\pi \times 8^2}{2} = 32\pi $ square inches. Option (A) is correct. Nikhil_dhama answered May 11, 2021 • selected May 11, 2021 by Arjun Nikhil_dhama 946 points comment Share Follow 0 reply Please log in or register to add a comment.
