Answer:

$A=2833.71\ cm^2$

Explanation:

Given that,

The height of the cylinder, h = 30 cm

The radius of the cylinder, r = 11 cm

We need to find the total surface area of the cylinder. The formula for the total surface area of the cylinder is given by :

$A=2\pi rh+2\pi r^2\\\\A=2\pi * 11* 30+2\pi * (11)^2\\\\A=2833.71\ cm^2$

So, the total surface area of the cylinder is
$2833.71\ cm^2$ .
