Solution

The correct option is C $2 π r (h + l)$
Total Surface Area of cylindrical part $= 2 π r h$
Surface Area of two cones $= π r l + π r l = 2 π r l$
Then, Total Surface Area $= 2 π r h + 2 π r l = 2 π r (h + l)$

The correct option is C 2πr(h+l)Total Surface Area of cylindrical part =2πrh Surface Area of two cones =πrl+πrl=2πrlThen, Total Surface Area =2πrh+2πrl=2πr(h+l)

The correct option is C $2 π r (h + l)$
Total Surface Area of cylindrical part $= 2 π r h$
Surface Area of two cones $= π r l + π r l = 2 π r l$
Then, Total Surface Area $= 2 π r h + 2 π r l = 2 π r (h + l)$
