How do I find the area of a half circle?

Since we know that a half circle stands for a semi circle, we just simply divide the equation by two to find the area of a semicircle. The formula for the area of a semicircle is A=pi * r^2/2

Step-by-step explanation: To find the area of a half circle or semi-circle, start with the formula for the area of a circle.

Area = πr²

Next, since a half circle is half the size of a circle, we just divide the area of a full circle by 2.
