lateral surface area of cylinder = 2πrh
= 13200cm².
capacity = πr²h = 22/7×35/2×35/2×120
= 115500cm³
in litre = 115500/1000 =115.5 litres.
= 13200cm².
capacity = πr²h = 22/7×35/2×35/2×120
= 115500cm³
in litre = 115500/1000 =115.5 litres.

lateral surface area of cylinder =2x22/7x35/2x120 (1.2x100=120cm) =60x22x10 =13200cm^2 capacity/volume = 22/7x35/2x35/2x120
=105x110
=11500cm^3 /1000 (cm^3/1000=liter)
=155.5 liters
=105x110
=11500cm^3 /1000 (cm^3/1000=liter)
=155.5 liters
