# Two cylindrical jars have their diameters in the ratio 3 : 1, but height 1 : 3. Then the ratio of their volume is

A. 4 : 1

B. 1 : 3

C. 3 : 1

D. 2 : 5

Answer :

Given,

Ratio of diameters of cylinders = 3:1

So, ratio of their radii = r_{1}:r_{2} = 3:1

Ratio of their heights = h_{1}:h_{2} = 1:3

So, ratio of their volumes = π(r_{1})^{2}h_{1} : π(r_{2})^{2}h_{2} =
