30 cm
The cylinder has a height of 30 cm and a radius of 11 cm. Work out the total surface area of
the cylinder. Give your answer correct to 2 significant figures.​

Answer 1

`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`.
