To find the length of monkey grass needed to go around a circular flower bed, you would use the formula for the circumference of a circle:
Circumference = 2πr
Given that the area is 36π, we can find the radius of the circle:
Area = πr^2
36π = πr^2
r^2 = 36
r = 6
Now, we can find the circumference:
Circumference = 2π(6)
Circumference = 12π
Therefore, you would need 12π feet of monkey grass to go around the circular flower bed. The correct answer is B.
Circumference = 2πr
Given that the area is 36π, we can find the radius of the circle:
Area = πr^2
36π = πr^2
r^2 = 36
r = 6
Now, we can find the circumference:
Circumference = 2π(6)
Circumference = 12π
Therefore, you would need 12π feet of monkey grass to go around the circular flower bed. The correct answer is B.
