Answer:

Let radius of 1st cylinder = r1

Let radius of 2nd cylinder = r2

According to question :

 \frac{r1}{r2}  =  \frac{ \sqrt{3} }{4}

Let height of 1st cylinder = h1

Let height of 2nd cylinder = h2

Volume of 1st cylinder = Volume of 2nd cylinder

\pi \:  {r1}^{2} h1 = \pi \:  {r2}^{2} h2 \\   {r1}^{2} h1 = {r2}^{2} h2 \\ \\    \frac{ {r1}^{2} }{ {r2}^{2} }  =  \frac{h2}{h1}  \\  \\ ( { \frac{r1}{r2}) }^{2}  =  \frac{h2}{h1}  \\  \\  ( { \frac{ \sqrt{3} }{4}) }^{2}  =  \frac{h2}{h1}  \\  \\  \frac{3}{16}  =  \frac{h2}{h1}  \\  \\  \frac{h1}{h2}  =  \frac{16}{3}

Therefore, The required ratio is 16 : 3.
