Answer: option C
Step-by-step explanation:
You need to use the formula for calculate the area of a circle:
[tex]A_{(circle)}=\pi r^2[/tex]
Where the radius of the circle is "r".
You can see in the figure that the diameter of the circle is 6 meters. Then you need to find the radius of the circle with the formula:
[tex]r=\frac{d}{2}[/tex]
Where "d" is the diameter of the circle.
Then, the radius is:
[tex]r=\frac{6m}{2}=3m[/tex]
Finally, substitute the radius into the formula. Then, the area of the circle is:
[tex]A_{circle}=\pi (3m)^2=9\pi m^2[/tex]
