A cylindrical storage tank has a radius of 4 meters and a height of 7 meters. Using π ≈ 3.14, what is the approximate volume of the tank?

✓ Correct Answer: Option C

The formula for the volume of a cylinder is V = πr²h. Substitute the values: V ≈ 3.14 × (4²) × 7 = 3.14 × 16 × 7 = 351.68 cubic meters.
