What is the area of a semicircle of a diameter Cm?
The area of a semicircle can be calculated using the formula ( A = \frac{1}{2} \pi r^2 ), where ( r ) is the radius. Since the diameter is given as ( Cm ), the radius ( r ) is ( \frac{Cm}{2} ). Plugging this into the formula gives ( A = \frac{1}{2} \pi \left(\frac{Cm}{2}\right)^2 = \frac{\pi (Cm)^2}{8} ). Thus, the area of the semicircle is ( \frac{\pi (Cm)^2}{8} ).
