Question

40.The ratio of heights of frustum of cones having same base 1:2 then the ratio of their volume

Answer 1

Answer:

It is given that, Height of cone and cylinder are same, let be h

Let the radius of cone be x

So, radius of cylinder be 2x

Volume of cone : volume of cylinder

⟹1π(x)2h:π(2x)2h

⟹1π(x)2h:π4(x)2h

⟹1:4
