Question

11 cm

Answer 1

Answer:

$A=2833.71\ cm^2$

Step-by-step 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 :

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

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