Answer: A. 622 sq. units
Step-by-step explanation:
The surface area of a cylinder is given by :-
[tex]S.A.=2\pi r(r+h)[/tex], where r is the radius , h is height of the cylinder.
Given : The height of the cylinder : h= 2 units
The radius of the cylinder : r= 9 units
Then , the surface area of a cylinder will be :-
[tex]S.A.=2(3.14159) 9(9+2)\\\\\Rightarrow\ S.A.=622.03482\approx622\text{sq. units}[/tex]
