Question

If the radius of two cylinder is same and height of one cylinder is double of the other cylinder

than ratio of their volume is​

Answer 1

Answer:

1:4

Step-by-step explanation:

Let the radius of two cylinders be x

And, height of one cylinder be y

Then, height of second cylinder = 2y

Ratio of volume of two cylinders = volume of first cylinder/volume of second cylinder =

22/7×x×x×y×y/22/7×x×x×2y×2y

= y×y/2y×2y

= 1/4

=1:4

Answer 2

Answer:

1:2

Step-by-step explanation:

volume of cylinder = pie×r²×h

let the radius and height of both cylinder be 1.

volume of 1st cylinder = pie × r² × h

= 22/7×1×1×1

= 22/7

volume of 2nd cylinder = 22/7×1×1×2 ( since the height of one cylinder is doubled the height of second cylinder will be 1×2)

= 44/7

Ratio= 22/7 ÷ 44/7

= 1/2

= 1:2 ans)
