The expressions would be [tex]\frac{90}{360} (36\pi )[/tex].
We have given that,
radius=6 units.
angle= 90 degrees.
What is the formula for the area of the sector?
The area of a sector is
[tex]Area of the sector=\frac{\theta}{360} \pi r^{2}[/tex]
Now, we're solving it by using this formula,
We have given that r=6 units and angle theta=90 degrees.
[tex]Area\ of \ the \ sector \ = \frac{90^0}{360} (\pi )6^{2}\\Area\ of \ the \ sector \ =9\pi[/tex]
But we only need the answer in uncompleted form thus the answer is:
[tex]\frac{90}{360} (36\pi )[/tex]
The expressions would be [tex]\frac{90}{360} (36\pi )[/tex].
Therefore option second is correct.
