Question

The radius of a semicircle is 3 inches what is the semicircles area

Answer 1

Answer:

9

Step-by-step explanation:

because radius is half then half in semicircle is 3

3x3 =9 now the answer is 9

Answer 2

Answer:

Hence, area of semicircle will be $\frac{99}{7}$ Sq. inch

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 = 3 inch

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,

$Area = \frac{1}{ 2}\Pi r^2\\=\frac{1}{2} \times \frac{22}{7} \times 3^2\\=\frac{1}{2} \times \frac{22}{7} \times 9 =\frac{11 \times 9}{7}= \frac{99}{7}\:inch^2$
