Find the surface area for the given cylinder with the radius 6 and the height 24

1130.97 is the surface area of the cylinder

Assuming the cylinder is closed at both ends

S A = 2 pi r^2 + pir^2h
       = 2 pi 6^2  + pi 6^2  24
       =  226.2 +  2714.3
       =    2940.5 

If the cyilnder is open at both ends  the surface area is 2714.3

Where’s the graph too show me?
