A cylindrical water tank has a diameter of 8 feet and a height of 10 feet. What is the approximate volume of the tank in cubic feet? (Use π ≈ 3.14)

✓ Correct Answer: Option B

The radius (r) is half the diameter, so r = 8/2 = 4 feet. The volume (V) of a cylinder is V = πr²h. V = 3.14 * (4)² * 10 = 3.14 * 16 * 10 = 502.4 cubic feet.
