Question
A cylindrical tank has a height of 12 meters and a
radius of 7 meters. If 50% of the tank is filled with water, what is the volume of water in the tank in cubic meters?Solution
The formula for the volume of a cylinder = π * r² * h. Given, radius r = 7 meters, height h = 12 meters. Full volume of the tank = (22/7) * (7)² * 12 = (22/7) * 49 * 12 = 1848 cubic meters. 50% of this volume = 1848 / 2 = 924 cubic meters.
