When you convert one solid into another one its volume remains same.

Volume of the metallic solid cone =.

where H and h are the heights of cone and cylinder, respectively.

Volume of the cylinder = πr²h

According to the question,

A metallic solid cone is melted to form a solid cylinder of equal radius. If the height of the cylinder is h cm, then the height of the cone is 3h.

Volume of the sphere =

Volume of the cone = Volume of n number of cones = According to the question,

If a sphere of radius r is melted to form a cone of radius and height 2r, then 2 cones can be made.
