Answer: option C
Step-by-step explanation:
You need to use the formula for calculate the area of a circle:
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:
Where "d" is the diameter of the circle.
Then, the radius is:
Finally, substitute the radius into the formula. Then, the area of the circle is:
