Answer: First, we need to find the radius of the base of the cone using the circumference formula:
Circumference = 2πr
8π = 2πr
r = 4
Now, we can use the formula for the volume of a cone:
Volume = (1/3)πr^2h
Substituting the values we have:
Volume = (1/3)π(4^2)(9)
Volume = (1/3)π(16)(9)
Volume ≈ 150.8 cubic feet
Therefore, the measurement closest to the volume of the cone in terms of pi is 150.8π cubic feet.
