Answer 1

\(2\pi r^{2} + 2\pi r h\) Go!!

Lids: \(2\pi r^{2}\)
Sides: \(2\pi r h\)

Answer 2

well he gave you formula
what else'd you need?

Answer 3

Formula: http://www.mathwarehouse.com/solid-geometry/cone/images/surface-area-of-cone/total-surface-formula-cone.jpg
\(\Large S_a=πrh_s+πr^2=πr\sqrt{r^2+h^2}+πr^2 \)
