Question

Find the surface area. 1 m 10 m

Answer 1

Answer:

$A=69.11\ m^2$

Step-by-step 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,

$A=2\pi \times 1(1+10)\\\\=69.11\ m^2$

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