Radius of cylindrical glass = 3.5 cm
Height up to the glass filled with milk = 12 cm
Volume of cylindrical glass = pi*r^2*h
= 22/7* 3.5*3.5* 12
= 3234/7
= 462 cm^3
Volume of 1 cylindrical glass = 462 cm^3
Volume of 1600 cylindrical glass = 1600*462
= 739200 cm^3
1000 cm^3 = 1 litre
739200 cm^3 = 739.2 litres
Therefore, 739.2 litres of milk is needed to serve 1600 students
