Question

what is formula for area for semi circle?​

Answer 1

Step-by-step explanation:

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.

Answer 2

Answer:

area of complete circle is πr^2

then area bounded by semi circle is πr^2/2
