Can someone help me? I’ll reward 10 points + brainalist (I want an explanation and answer)

Answer:
B
Step-by-step explanation:
The area of a circle is
[tex]\pi {r}^{2} [/tex]
where r is the radius.
A radius is a line segment from the center of the circle to the circumference of a circle(any point that is on the arc).
It is given that x=1/3 so we use this equation.
Substitute 22/7 for pi
[tex] \frac{22}{7} ( \frac{1}{3} ) {}^{2} [/tex]
[tex] \frac{22}{7} \times \frac{1}{9} [/tex]
[tex] \frac{22}{63} [/tex]
Area is squared so we use in^2.
B is the answer
