Find the surface area of a cylinder with a height of 7m and a base diameter of use the value of 3.14 for pie. and do not do any rounding, be sure to include the correct unit.
Answers: 1
![\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=4\\ h=7 \end{cases}\implies SA=2\pi (4)(7+4) \\\\\\ SA=8\pi (11)\implies SA=88\pi \implies \stackrel{\pi =3.14}{SA=276.32}](/tpl/images/0041/3316/0ea1d.png)
