“A pillar 14 cm in diameter and 5 m high contains how much material?”

"Calculating the volume of a cylindrical pillar with a 14 cm diameter and 5 m height involves the formula for a cylinder’s volume: πr²h. Converting 5 m to 500 cm the radius is 7 cm (half of 14 cm). Using π ≈ 22/7 the volume is (22/7) × 7² × 500 = 22 × 7 × 500 = 77000 cm³ or (77×10³) cm³. This represents the material used critical in construction for estimating resources. The calculation highlights the application of geometric principles in real-world engineering and material science."
