A semicircle is a half circle which is formed from a whole circle when the circle is cut along the diameter. When a circle is cut along the diameter line it is always divided into two equal halves.

## Area of Semicircle

Area of semicircle is said to be half the area of circle, it is given as:

*Area = (Ď€r**Â˛)/2*

Where** r** is the radius of semicircle.

## Perimeter of Semicircle

The perimeter of semicircle is unlike area of semicircle not equal to half the perimeter of circle.

*Perimeter = Ď€r + 2r*
