Question
A cylindrical water tank has a radius of 7 m and a
height of 10 m. How much water will the tank hold in liters?Solution
The volume of a cylinder is given by the formula: Volume = πr²h Substitute the given values: Volume = π × 7² × 10 = π × 49 × 10 = 490π Now, approximate π = 3.14: Volume = 490 × 3.14 = 1538.6 m³ Since 1 m³ = 1000 liters, the volume in liters is: 1538.6 × 1000 = 1,538,600 liters Correct Option: d
