What is area of a semicircle when radius is given?

The area of a semicircle when the radius is given is the region occupied by the semicircle in a two-dimensional plane of radius "r". A semicircle is a half-circle. That means a semicircle will have half of the area of a circle. Therefore, to find the area of a semi-circle, you just have to find the area of a full circle and then divide it by two.
