Answer:
The height of the smaller cone is 19.52 cm
Explanation:
Given that,
The volume of cone 1, V₁ = 3970 cm³
The volume of cone 2, V₂ = 3100 cm³
The height of the larger cone, h₁ = 25 cm
We need to find the height of the smaller cone. Let it is h₂. For similar cones,

Put values,

So, the height of the smaller cone is 19.52 cm.
