Options:

4 : 3

1 : 3

16 : 9

3 : 1

Correct Answer:

1 : 3

Explanation:

Cylinder :        1st                    2nd

Radius   :         3           :          4

Heights :         16          :          27

Volume  :     \(\pi \)(r1)2h1    :    \(\pi \)(r2)2h2

             :     \(\pi \)(3)2 16    :    \(\pi \)(4)2 27

             :           1          :           3
