A Correct answer
Explanation

Volume of a cylinder = pi * r^2 * h. Here, r = 7, h = 12. Volume = (22/7) * 7 * 7 * 12 = 22 * 7 * 12 = 1848 m^3. Since the tank is half-filled, the volume of water is 1848 / 2 = 924 m^3.

AI explanation

The total volume of the cylindrical tank is given by the formula pi times the radius squared times the height, which is (22/7) times 7 squared times 12. This calculation gives a total volume of 1848 m3. Since the tank is half-filled, the volume of the water is 1848 divided by 2, resulting in 924 m3.
