Question

The diameter of two cylinder's are in the ratio 2:3,then the ratio of their heights,if their volumes are the same is​

Answer 1

d₁ : d₂ =2:3

h₁ : h₂ = ?

r₁ : r₂ = 1:1.5

v₁ = v₂

∴πr²₁ r₁ = πr₂h₂

∴1²h₁ = 1.5²

∴ h₁ / h₂ = 2.25/1

= 9 / 4

So,the Required Ratio is 9 : 4

Answer 2

Required Ratio is 9 : 4......
