Formula for "S.A." (Surface area) of a cylinder

S.A. 
= 2 [tex] \pi [/tex] r² + 2[tex] \pi [/tex] * r * h ;
_______________________________________
in which "r" = length of radius of circle at the end; and "h" = "height" ; 
__________________________________________
Given: r = 2 m ; and h = 3 m ; 
__________________________________________
 We can "plug in" these given values; and solve for the "surface area" in terms of
"[tex] \pi [/tex]" .
____________________________________________
S.A. = 2 [tex] \pi [/tex] r² + 2[tex] \pi [/tex] * r * h ;
    
         = 2 [tex] \pi [/tex] * (2)²   + 2 [tex] \pi [/tex] * (2)  * (3)  ;
         
         =  2 [tex] \pi [/tex] * (4)   + 2 [tex] \pi [/tex] * (6) ;
   
         =  (8 [tex] \pi [/tex])   +     (12) [tex] \pi [/tex] 

         =    20 [tex] \pi [/tex]   m²  .
