A school provides milk to its students in cylindrical glasses, each with a diameter of 7 cm. If each glass is filled with milk to a height of 12 cm, how many litres of milk are needed to serve 1600 students? Use 1000 cm³ = 1 litre.

With radius 3.5 cm and height 12 cm, one glass holds (22/7) × 3.5² × 12 = 462 cm³. For 1600 students, total milk is 1600 × 462 = 739,200 cm³ = 739.2 litres.

    1. The diameter is 7 cm, giving radius r = 3.5 cm and height h = 12 cm. Volume per glass is πr²h = (22/7) × (7/2) × (7/2) × 12 = 22 × 7 × 3 = 462 cm³. For 1600 students, the total milk needed is 1600 × 462 = 739,200 cm³. Using the conversion 1000 cm³ = 1 litre, this equals 739,200 / 1000 = 739.2 litres of milk.
