Just enter the value of radius in the area of a semicircle calculator to compute the semicircle area within a blink of an eye. Area of a Semi-Circle: A semi-circle is half of a circle. Area of semi-circle formula is derived from the formula of a circle.


Area of a Semicircle Calculator 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.

Additional Information A semi-circle (or semicircle) is simply one-half of circle. It can also be thought of as a sector with an angle of 180 degrees. If the perimeter of the semi-circle is needed, add together the lengths of one-half of the circumference + diameter: Where (for brevity) it says 'radius', 'circumference' and so on, it should, more correctly, be something like 'l...


To find the area of a semicircle, start by finding the area of the full circle using the formula πr^2, where r is the radius of the circle. If you don't know the radius, you can find it by dividing the diameter of the circle by 2. Once you've found the area of the full circle, just divide it by 2 to find the area of the semicircle.
