Question

A milk tank is in the form of 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.

Answer 1

Radius of cylinder = 1.5 m 
Length of cylinder = 7 m 
Volume of cylinder = \(\pi r^2h\)
\(= (\frac{22}{7})×1.5×1.5 ×7\)
= 49.5 cm³
= 49.5\(×\)1000 liters = 49500 liters
1m³ = 1000 L
Required quantity = (49.5 \(×\) 1000) L= 49500 L 
Therefore, 49500 L of milk can be stored in the tank.
