Question

the radii of two cylinders are in ratio 2:3 and their heights in ratio 5:3.Find the ratio of volumes ​

Answer 1

20ratio27 is the correct answer

Answer 2

$= \frac{\pi {r}^{2}h }{\pi {r}^{2 }h } \\ = \frac{ {r}^{2}h }{ {r}^{2} h} \\ = \frac{4 \times 5}{9 \times 3} \\ = \frac{20}{27}$

ratio = 20:27
