Answer 2

\[\frac{ 15 }{ 6 } = \frac{ 5 }{ x }\]

Answer 3

There's a few ways of looking at this:

You can solve for x by comparing the ratios between the 2 cylinders:
H\H' = r\r'

15\5 = 6\x

x = 6\(15\5)

Or, as Kanwar did it, you can solve for x by taking the H\r ratio of one cylinder and projecting it onto the other.

H\r = H'\r'

15\6 = 5\x

x = 5\(15\6)
