Answer :

Let V1 be the volume of first cone and V2 be the volume of second cone.

Then, V1:V2 = 1:4

Let d1 be the diameter of first cone and d2 be the diameter of second cone.

Then d1:d2 = 4:5

Let h1 be the height of first cone and h2 be the height of second cone.

We know that volume of cone is given by V = 1/3 × π(d2/4)h

h1:h2 = 25:64

Ratio of height of two cones is 25:64.
