Question

If radius of the semicircle is ‘r', then area of the semicircle is

Answer 1

Hey friend,

Here is your answer,

Given : radius of semicircle = r

To find : area of semicircle

Solution :

Since area of a circle = π(r^2)

Therefore, area of a semicircle would be 1/2(area of full circle) = 1/2×π×r^2

Therefore,

The required area of a semicircle is
1/2(π)(r^2)

Where 'r' is the radius of the circle.


Hope it helps you.
Thank you.

Answer 2

Answer:

Hence, area of semicircle will be $\frac{1}{2} \Pi r^2$ Sq. cm

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 = r cm

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,

$Area = \frac{1}{ 2}\Pi r^2$
