[AI-generated answer — Bot GPT 3.5]

To find the circumference of the circular flower bed, you would use the formula C = 2πr, where r is the radius of the circle.

Since the area of the circle is given as 36π, you can find the radius by taking the square root of the area divided by π:

r = √(36π/π) = √36 = 6

Therefore, the radius is 6 feet.

Now, to find the circumference, you would use the formula C = 2π(6) = 12π feet.

Therefore, you would need 12π feet of monkey grass to go around the circular flower bed, which is option B.
