Question

A milk tank is in the form of a cylinder whose radius is 1.4 and length 7m. find the quantity of milk(in litres) that can be stored in a tank

Answer 1

quantity of milk= volume of cylinder tank

$volume \: of \: cylinder = \pi {r}^{2} h$
$= \frac{22}{7} \times 1.4 \times 1.4 \times 7 \: \: m$
$= 40.34 \: {m}^{3}$
we know,

$1 {m}^{3} = 1000 \: litres$

$40.34 {m}^{3} = 40.34 \times 1000$

$= 403400 \: litres$
