Question

prove that area of semicircle is half of the area of circle

Answer 1

Answer:

πr² ÷ 2

Step-by-step explanation:

We know that what a semi-circle is.

A semi-circle is half of the circle.

∴ Its area will also be half of the circle, ie, πr² ÷ 2.

For example, if the radius of a circle is 7 cm, then area of the circle will be

22/7 * 7 * 7= 22*7 = 154 cm².

Area of a semi-circle with the same radius will be 154/2 = 77 cm².
