Answer:
The correct option is B.
Step-by-step explanation:
The area of a circle is
[tex]A=\pi r^2[/tex]
where, r is the radius of the circle.
The radius of the given circle is 6 units.
The area of given circle is
[tex]A=\pi (6)^2[/tex]
[tex]A=\pi (36)[/tex]
[tex]A=36\pi[/tex]
The area of complete circle is 36π units².
From the given figure it is clear that 1/4th part of circle is shaded. The area of 1/4 th circle is
[tex]A_1=\frac{1}{4}A[/tex]
[tex]A_1=\frac{1}{4}(36\pi)[/tex]
[tex]A_1=9\pi[/tex]
The area of shaded sector is 9π units². Therefore, the correct option is B.
