Answer:

Step-by-step explanation:

V = 108π in³

h = 4 in

r = √(3V/(πh)) = 9 in

Answer:

B

Step-by-step explanation:

If you have 108 pi and then you divided it to find the radius and all that stuffy stuff you will end up getting 9 and if you dont want to do it that way just substitute each one of the answer chooses as the radius until the volume gets you 108 pi cubic inches.
