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 = (πr²)/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 = πr + 2r
