Question

13. A mik tank is in the form of cylinder whose radius is 1m
and length is 7m. Find the quantity of milk in litres
that can be stored in the tank. Also find the area of
metal sheet required to make it​

Answer 1

• It is given that the milk tank is in the form of a cylinder whose radius is 1.5m and length is 7m.

• Length of milk tank = height of the cylinder

Now,

• Radius of the cylinder = 1.5 m
• Height of the cylinder = 7 m

We know( formula ),

• Volume of cylinder = πr² h

Therefore,

• Volume of the milk tank = πr² h

       ⇒

$\dfrac{22}{7}\times (1.5 m)^2 \times 7 m$

       ⇒ 22 x 2.25 m² x m

       ⇒ 49.5 m³

We know,

•  1 m³ = 1000 liters

So,

• 49.5 m² = 49,500 liters

Therefore,

49,500 liters of milk can be stored in the tank.
