The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle. Since the area of the flower bed is given as 36π ft^2, we can calculate the radius of the circle using the formula A = πr^2:
36π = πr^2
36 = r^2
r = 6 ft
Now, substitute the radius back into the circumference formula to find the length of monkey grass needed:
C = 2π(6)
C = 12π feet
Therefore, you would need 12π feet of monkey grass to go around the circular flower bed.
