A semicircle is nothing but half of the circle. So the area of a semicircle is when you cut a full circle into half you get the area of a semicircle. We know the formula to calculate area of a circle is πr^2, by dividing this by 2 we will get the area of a semicircle.

r = radius of the semicircle

In the below online area of a semicircle calculator, enter the radius in the input box and then click calculate button to find the answer.
