Question

Find the surface area.
1 m
10 m

Answer 1

`A=69.11\ m^2`

Explanation:

Given that,

The radius of cylinder, r = 1m

Height of the cylinder, h = 10 m

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

`A=2\pi r^2+2\pi rh\\\\A=2\pi r(r+h)`

Put all the values,

`A=2\pi * 1(1+10)\\\\=69.11\ m^2`

So, the surface area of the cylinder is equal to
`69.11\ m^2`.
