HI CYLINDER   RAD 5CENT    HEIGHT 10CM

SURFACE AREA  FORMULE IS   TOP     Pi x r x r          BOTTOM   Pi x r x r    SIDE 2Pi X r x h

THEREFORE  Pi = 22/7               22/7 X 5 X 5 = 550/7  = 78.57 SQ CM       BOTTOM THE SAME

SIDE  2 X 22/7 X 5 X 10 = 2200/7 = 314.285  TOTAL SURFACE AREA  = 78.57+78.57+314.285= 471.42571 sq cm

HOPE THIS HELPS
