Question
A cylindrical water tank has a height of 12 meters and a
radius of 3 meters. How many liters of water can the tank hold? (Use π = 3.14 and 1 cubic meter = 1000 liters)Solution
Volume of the cylinder = πr²h = 3.14 × (3)² × 12 = 3.14 × 9 × 12 = 339.12 cubic meters = 339.12 × 1000 = 339,120 liters.
