Question

Which of the following is the surface area of the right cylinder below radius 7 height 2

Answer 1

7^2 times 2 which is 49.2 and it is 98

Answer 2

$\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\ -----\\ r=7\\ h=2 \end{cases}\implies SA=2\pi (7)(2+7) \\\\\\ SA=14\pi (9)\implies SA=126\pi$
