Question

Find the volume and surface area

Answer 1

$\bf \begin{array}{llll} \stackrel{\textit{volume of a cylinder}}{V=\pi r^2 h}\\\\ V=\pi (8)^2(3)\\\\ V=192\pi \\\\ V\approx 603.19 \end{array}~\hfill \begin{array}{llll} \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=8\\ h=3 \end{cases} \end{array}~\hfill \begin{array}{llll} \stackrel{\textit{surface area of a cylinder}}{SA=2\pi r(h+r)}\\\\ SA=2\pi (8)(3+8)\\\\ SA=16\pi (11)\\\\ SA=176\pi \\\\ SA\approx 552.92 \end{array}$
