How can you find the area of a semi-circle

In the case of a circle, the formula for area, A, is A = pi * r^2, where r is the circle's radius. Since we know that a semicircle is half of a circle, we can simply divide that equation by two to calculate the area of a semicircle. So, the formula for the area of a semicircle is A = pi * r^2/2

Area of semi-circle is πr²/2.

Step-by-step explanation:

Area of circle is πr² where r is radius of the circle.

Semi-circle is defined as the half circle.

So, the area of the semi-circle is half of the area of circle.

Area of semi-circle=area of circle/2

So , Area of semi-circle =πr²/2 which is the answer.

darn right!
