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.

To find the perimeter of a semi circle, you have to know the diameter (the length of its straight edge). For example, if the diameter of your semi circle is 12 centimeters, the formula becomes P = 1/2 (3.14 × 12) + 12.

A semicircle is one half of a circle. It looks like a straight line with a circular arc connecting its ends to one another. The straight edge of the semicircle is the diameter and the arc is half the circumference of a full circle with the same diameter. You can find the radius of a semicircle using the formulas for circumference and diameter.
