Question

if the radius of two cylinder are in ratio 2:3 and there hight are in ratio 5:3 then what is the ratio of there volume

Answer 1

2:3:5:3.
I hope this is the answer.

Answer 2

hello users ...

solution:-
we know that:
volume of cylinder = πr²h 

Here,
according to given :
let Radius of first cylinder = 2r
And
Radius of second cylinder = 3r

Also,
let the height of first cylinder = 5h
And
height of second cylinder = 3h

Now,
volume of first cylinder = πr²h

= π (2r)² 5h 
= π×(4r² )× 5h 
= 20 × πr²h 

And
the volume of second cylinder = πr²h

= π (3r)² 3h 
= π×(9r²)×3h 
= 27 × πr²h

Now,
The ratio between their volumes = volume of first cylinder / volume of second cylinder

= 20 πr²h / 27 πr²h 
= 20 / 27 = 20 : 27 Answer
