Answer:

Since there is no drawing of the semicircle, the steps to solve this question are explained.

The area is given by:


A = 1.57r^2

Explanation:

Area of a semi-circle:

The area of a semi-circle is given by the following equation:


A = (\pi r^2)/(2)

In which r is the radius.

Use 3.14 for pi​


A = (\pi r^2)/(2) = (3.14r^2)/(2) = 1.57r^2

r is the radius, which is the distance from the centre of the circle to an edge, or half the distance between two edges, which is the diameter.
