Question

4. A milk tank is in the form of a cylinder whose radius is 1.8 m and height is 14 m. Find the
quantity of milk in litres that can be stored in the tank.

​

Answer 1

Given:

Radius = 1.8 m

Height = 14 m

Therefore, volume of the tank

$= ( \frac{22}{7} \times 1.8 \times 1.8 \times 14)m^{3} \\ = 142.56 m^{3}$

We know,

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

Quantity of milk that can be stored in the tank

$= (142.56 \times 1000)litres \\ = 142560 \: litres$

Answer:

The quantity of milk that can be stored in the tank is 142560 litres.
