Question

If a solid cone of base radius r and height h is placed over a solid cylinder having the same base radius and height as that of the cone, then the curved surface area of the solid so formed is ______.

Answer 1

If a solid cone of base radius r and height h is placed over a solid cylinder having the same base radius and height as that of the cone, then the curved surface area of the solid so formed is `underlinebb(πr(sqrt(h^2 + r^2) + 2h))`.

Explanation:

Here, the cone’s slant height is \[\sqrt{h^{2}+r^{2}}\].
