Area of a Semicircle Formula. Because a semicircle is exactly half of a circle, then the area of semicircle must be exactly half that of the area of a circle. By the way, the prefix semi- means half. That means, if the area of a circle is [latex]\large{A = \pi {r^2}}[/latex]
So 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.
