Answer 1

Answer:

646.8 litres

Step-by-step explanation:

$d = 7cm \\ r = \frac{7}{ 2}cm \\ h = 12cm \\ volume \: of \: cylinder = \pi \: {r}^{2} h \\ = \frac{22}{7} \times \frac{7}{2} \times \frac{7}{2} \times 12 \\ = 77 \times 6 \\ = 463cube.cm \\ no. \: of \: litres \: for \: 1400 \: students = 462 \times 1400 \\ = 646800 \\ divide \: by \: 1000 \: to \: get \: answer \: in \: litres \\ = \frac{646800}{1000} \\ = 646.8litres$
