Answer :

The ratio of their volumes is **9:32**.

**Given:** heights are in ratio 1:2

Perimeters of bases are in ratio 3:4

**Formula Used:**

The volume of cone =

**Explanation:**

Let height be H and h

Radius be R and r

Acc. to question,

⇒ h = 2H

As the bases are circular,

The perimeter of base = 2πr

Acc. to question,

Now,

Hence, the ratio of their volumes is 9:32.
