Answer 2

Answer:

Hence, area of semicircle will be 77 Sq. unit

Step-by-step explanation:

In context to question asked,

We have to determine the area of semicircle

As per data given in the question,

We have,

Radius of semicircle = 7 unit

As we know that,

Area of semicircle is half the area of circle.

So, formula for finding area of semicircle will be $\frac{1}{2} \Pi r^2$

So, for finding the area of semicircle we will put the value of radius of semicircle in above formula

Thus we will get,

$Area = \frac{1}{ 2}\Pi r^2\\=\frac{1}{2} \times \frac{22}{7} \times 7^2\\=\frac{1}{2} \times \frac{22}{7} \times 49 =11 \times 7= 77\:unit^2$
