Let the height of both the cylinder and the cone be \(h\) units, and the radius be \(r\) units. \(\therefore\) Volume of the cylinder = \(\pi r^2 h\) \(= 3 \times \frac{1}{3} \pi r^2 h\) \(= 3 \times\) Volume of one cone \(\therefore\) By melting a solid cylinder, 3 solid cones of the same radius and height can be made.
