Question

Where is the centre of gravity placed in a solid cone and a hollow cone?

Answer 1

solid cone is h/4 from the base

hollow cone is h/3 from the base

Answer 2

In solid cone it is at a height of h/4 from the base of the cone on its axis.

In hollow cone it is at a height of h/3 from the base of the cone on its axis.

Axis means the central line joining the upper vertex of the cone and the midpoint of its base.
