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.
How many feet of monkey grass would you need to go around a circular flower bed if you know that the area is 36π ?
A: 6π feet
B: 12π feet
C: 18πfeet
D 36π feet
E: 144π feet
