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

Answer: Fourth option is correct.
Step-by-step 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:
[tex]A=\frac{\pi r^2S}{360}[/tex]
Now, we want to solve it for 'S'.
So, it will become,
[tex]A=\frac{\pi r^2S}{360}\\\\360A=\pi r^2S\\\\\frac{360A}{\pi r^2}=S[/tex]
Hence, Fourth option is correct.
