The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.
Given that the area of the circular flower bed is 36 ft^2 π, we can find the radius by using the formula for the area of a circle: A = πr^2.
36 ft^2 π = πr^2
36 ft^2 = r^2
r = 6 ft
Substitute the radius into the formula for the circumference:
C = 2π(6)
C = 12π feet
Therefore, the answer is B: 12π feet.
How many feet of monkey grass would you need to go around a circular flower bed if you know that the area is 36 ft2 π ?

C: 18πfeet
D: 36π feet
E: 144π feet
