Answer variants:
\( \pi r (l + r)\)
\(l = \sqrt{r^2 + h^2}\)
\( 2 \pi r (l + r)\)
\(l^2 = \sqrt{r^2 + h^2}\)
1. If \(r\) be the radius and \(l\) be the slant height of the right circular cone, then the total surface area \(=\)
2. If \(r\) be the radius and \(h\) be the height, then the slant height \(l\) of the right circular cone \(=\)
