Explanation: Find the volume of the larger tank:

Radius of the larger tank = Diameter / 2 = 2.4 m / 2 = 1.2 m

Volume of a cylinder = π radius² height

Volume of the larger tank = π (1.2 m)² 6.4 m

Volume of the larger tank ≈ 28.94 m³

2. Find the volume of the smaller containers:

Radius of the smaller container = 8.2 cm / 100 = 0.082 m

Height of the smaller container = 28 cm / 100 = 0.28 m

Volume of a smaller container = π (0.082 m)² 0.28 m

Volume of a smaller container ≈ 0.00059 m³

3. Calculate the number of smaller containers:

Number of containers = Volume of larger tank / Volume of smaller container

Number of containers ≈ 28.94 m³ / 0.00059 m³

Number of containers ≈ 49050.84

4. Since we can only have whole containers:

Number of complete smaller containers = 49050

Therefore, approximately 49050 smaller cylindrical containers can be completely filled using the oil from the larger tank.
