Question

Find the ratio of volume of cylinder whose heights are equal and radius are in the ration 2:5

Answer 1

volume = 157. 08

i can not do explaination

Answer 2

Answer:

• ratio of the volumes will be 4:25.

Step-by-step explanation:

let there volumes are V and V'.

volume of first cylinder V=πr^2h

and volume of second cylinder V'=πr'^2h'

now ratio of their volumes

v/v'=πr^2h/πr^2h'

=(r/r')^2 {h=h'}

=(2/5)^2

=4/25

• hence ratio of their volumes will be 4:25
