WebSep 22, 2024 · Since we know that a semicircle is half of a circle, we can simply divide that equation by two to calculate the area of a semicircle. So, the formula for the area of a semicircle is A = pi * r ^2/2. WebJul 4, 2016 · We then compute sum of the area of many small rectangles which will cover all the area of the semi-circle. Putting that in "integral term" and knowing that the area is actually $\pi R_0^2 /2$ we can conclude : $$ \int_{-R_0}^{R_0} f(r)\ dr = \pi \frac{R_0^2}{2} $$ Therefore your integral will be $\pi R_0^2 /4$.
