A. the volume of cylinder B is half the volume of cylinder A

B. the volume of cylinder B is twice the volume of cylinder A

C. the volume of cylinder B is 4 times the volume of cylinder A

If you were to stack two of cylinder A, one on top of the other, you would have the equivalent of cylinder B.

The appropriate choice is ...
  B. the volume of cylinder B is twice the volume of cylinder A

Answer: B is the answer..

Step-by-step explanation:

 V A = πr2h= π (3)2 (6) = 3.14 ( 9) (6)= 169.56 in3
V B = πr2h= π (3)2 (12) = 3.14 ( 9) (12)= 339.12 in3

Since the VB has the height is doubled...so you know right away , the Volume of cylinder B will be double of cylinder A..
