Question

The height of a soft drink is about 12 centimeters and the diameter is about 6 centimeters find the surface area of the can

Answer 1

if the diameter of the can is 6 cm, then its radius is half that, or 3 cm.

$\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\ \cline{1-1} r=3\\ h=12 \end{cases}\implies SA=2\pi (3)(12+3) \\\\\\ SA=6\pi (15)\implies SA=90\pi \implies SA\approx 282.74$
