Question

Find the area of the semicircle .

Answer 1

The area of the semi-circle is 56.571 sq. unit.

How did we get the value?

Given that,

Radius of semi circle = r = 6

Area of semi circle = (
`πr^2`)/2

= (½) × (22/7) × 6 × 6

= 56.571

Therefore, the area of the semi-circle is 56.571 sq. unit.

Answer 2

area of semicircle formula :
1/2 x pi x radius x radius

so ,
1/2 x pi x 6 x 6
= 56.5486678....
≈ 56.55 ( 2 decimal place )
