Our Area of a Semicircle Calculator will find the area of any semicircle, if you type in a radius or diameter. It will take whole numbers, fractions or decimal values. The best thing about it is that it shows the working out, step-by-step.
Area of a Semi Circle Formula The area of a semicircle is equal to half of the area of the whole circle. So the area of a semicircle is ½ πr 2 , where r is the radius of the circle.

We can use the distance formula using its endpoints to calculate the diameter’s length, then divide it by [latex]2[/latex] to get the radius’s value. Finally, use the semicircle formula to find its area by substituting the radius value.
The formula which is used to calculate the area of the semicircle is expressed as, Area of semicircle (when the radius is given) = πr 2 /2, Area of semicircle (when the diameter is given) = πd 2 /8, where 'r' is the radius, and 'd' is the diameter.
