Answer:
The surface area of this cylinder is 36pi.
Step-by-step explanation:
The surface area of a cylinder is given by:
[tex]S = \pi r^{2}h[/tex]
In which r is the radius and h is the height.
In this question:
[tex]r = 2, h = 9[/tex]
Then
[tex]S = \pi*2^{2}*9 = 36\pi[/tex]
The surface area of this cylinder is 36pi.
