SURFACE AREA OF CYLINDER :-
If, radius of cylinder=r
height of cylinder=h
Then, curved surface area of Cylinder=2πrh
The Total surface area of Cylinder=2πr(r+h)
Ex:-
If, radius of cylinder=r=35cm
height of cylinder=h=10cm
hen, curved surface area of Cylinder=2πrh
=2x(22/7)x35x10
=2x22x5x10
=2200 cm2
The Total surface area of Cylinder=2πr(r+h)
=2x(22/7)x35(35+10)
=2x22x5x45
=9900 cm2
