प्रश्न
A milk tank is in the form of a cylinder whose radius is 1.5 m and length is 7 m. Find the quantity of milk in litres that can be stored in the tank?
उत्तर
Radius of cylinder = 1.5 m
Length of cylinder = 7 m
Volume of cylinder = πr2h
= `(22/7 xx 1.5 xx 1.5 xx 7)m^3`
= 49.5 m3
1m3 = 1000 L
Required quantity = (49.5 × 1000) L
= 49500 L
Therefore, 49500 L of milk can be stored in the tank.
