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

Respuesta :

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

[tex]\bf \textit{surface area of a cylinder}\\\\ SA=2\pi r(h+r)~~ \begin{cases} r=radius\\ h=height\\ -----\\ r=3\\ h=12 \end{cases}\implies SA=2\pi (3)(12+3) \\\\\\ SA=6\pi (15)\implies SA=90\pi [/tex]
