True and False Statements
A solid cone of radius \( \mathrm{r} \) and height \( \mathrm{h} \) is placed over a solid cylinder having same base radius and height as that of a cone. The total surface area of the combined solid is \( \pi \mathrm{r}\left[\sqrt{\mathrm{r}^{2}+\mathrm{h}^{2}}+3 \mathrm{r}+2 \mathrm{~h}\right] \).
