C 18π feet
To find the amount of monkey grass needed to go around the circular flower bed, you would need to calculate the circumference of the circle. The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle. Since the radius is not given, we can use the formula for the area of the circle to find the radius.
A = πr^2
36π = πr^2
r^2 = 36
r = 6
Now, we can find the circumference of the circle:
C = 2πr
C = 2 * π * 6
C = 12π feet
Therefore, you would need 12π feet of monkey grass to go around the circular flower bed.
How many feet of monkey grass would you need to go around a circular flower bed if you know that the area is 36π
?
