Question

The base radii of two cylinders are in the ratio 4:5. Find the ratio of their volumes.​

Answer 1

Step-by-step explanation:

$let \: \: the \: \: radii \: \: be \: \: 4x \: \: and \: \:5x \: \: respectively \\ volume = {\pi (r )^{2} h} \\ ratio \: = \frac{\pi {(4x)}^{2} h}{\pi {(5x)}^{2}h } \\ = \frac{16}{25} \\ ratio \: = 16 : 25$
