Question

volume of aa cylinder is in joint variation with square of the length of the radius of base and its height. Ratio of radius of bases of two cylinders is 2:3 and ratio of their heights is 5:4, let us find the ratio of their volumes.i​

Answer 1

Answer:

Acc. To given condition:

Volume of cylinder ∝ (radius)2(height)

V ∝ (r)2(h)

Radius of two cylinders = r1 : r2 = 2 : 3

Heights of two cylinders = h1 : h2 = 5 : 4

Volume of two cylinders = v1 : v2

Then, the ratio of their volumes = 5 : 9.
