Question

The area of a sector of a circle is given by the equation

Answer 1

`A= ( \pi r^(2) S)/(360)`

`360A= \pi r^(2) S`

`(360A)/( \pi r^(2) ) = S`

So the answer is D. Hope this helps :)

Answer 2

Answer: Fourth option is correct.

Explanation:

Since we have given

S be the angle of sector.

r be the radius of the sector.

A be the area of the sector .

Now, we have given the equation:

`A=(\pi r^2S)/(360)`

Now, we want to solve it for 'S'.

So, it will become,

`A=(\pi r^2S)/(360)\\\\360A=\pi r^2S\\\\(360A)/(\pi r^2)=S`

Hence, Fourth option is correct.
