Answer: C. [tex]126\pi \text{units}^2[/tex]
Step-by-step explanation:
The surface area of right cylinder is given by :-
[tex]S.A.=2\pi r(r+h)[/tex]
Given : Height : h=2 units
Radius : r= 7 units
The the surface area of the given right cylinder will be :-
[tex]S.A.=2(\pi) (7)(2+7)\ \ \ \text{Put }\pi=3.14[/tex]
i.e. [tex]S.A.=126\pi \text{units}^2[/tex]
Hence, the surface area of the right cylinder = [tex]126\pi \text{units}^2[/tex]
