Question

Find the area of the semicircle.

Answer 1

Given:

Given that the radius of the semicircle is 4 units.

We need to determine the area of the semicircle.

Area of the semicircle:

The area of the semicircle can be determined using the formula,

`A=(\pi r^2)/(2)`

Substituting π = 3.14 and r = 4, we get;

`A=(3.14 * (4)^2)/(2)`

Simplifying, we get;

`A=(3.14 * 16)/(2)`

Multiplying, we get;

`A=(50.24)/(2)`

Dividing, we get;

`A=25.12`

Thus, the area of the semicircle is 25.12 square units.
