Hi Dear !
____________________________________________________________
The metal pipe(cylinder):
diameter           (d) =  4 cm 
Inner radius     (r)  = 2 cm 
Outer diameter(D) = 8 cm 
Outer radius    (R) = 4cm 
Height              (h) =  77cm 
_____________________________________________________________
TSA Of the Given Cylinder = 2 pi r (h + r ) - 2 pi R ( h + R)
                                              = 2036.57         - 993.14
                                              = 1043.43 cm 2
