A= 69 m

Steps:

First we have to find the diameter of the circle. The diameter is a straight line that passes through the circle. Since we know the radius is 11 m, we can multiply that by 2 to get the diameter.

Diameter- 22 m

Now we multiply the diameter by Pi (3.14) and we get 69.08 m

We would round 69.08 to 69, or to be less specific, 70.

I hope this helped! Please correct me if I’m wrong.
