Question
The radius of a cylindrical tank is 7 meters, and its
height is 14 meters. How much water will it take to fill the tank to half its capacity?Solution
Volume of the cylinder = πr²h. For a full tank, volume = π × (7)² × 14 = π × 49 × 14 = 686π m³. Half the capacity of the tank = 686π / 2 = 343π m³. Correct answer: c. 343π m³
