Question

The radii of two cylinders are in the ratio 1 : 2. Find the ratio of their heights, if their volumes are same​

Answer 1

Step-by-step explanation:

$\frac{r1}{r2} = \frac{1}{2}$

$volume \: of \: first \: cylinder = volume \: of \: second \: cylinder \\ \pi {r}^{2} h1 = \pi {r}^{2} h2 \\ {1}^{2} h1 = {2}^{2} h2 \\ \frac{h1}{h2} = \frac{4}{1}$
