WebSo we derive the formula for the area of a semicircle as $(\pi r^{2})/2$, which is half the area of a circle. Also, the surface area of the semicircle formula is the same as the area of the semicircle formula. Area of semicircle $=\frac{\pi r^{2}}{2}$ Fun Facts! Semicircle is obtained by cutting the circle into two exactly equal halves. WebI first recognized the shape to be half a cone. The volume to calculate the volume of a cone is (pi*r^2*h)/3. To get half a cone, I divided that by 2, giving me the formula ( (pi*r^2*h)/3)/2. From here on, I only need to substitute in the values for r and h to get the correct answer.
