Applications
Essential for construction (calculating concrete for pillars), manufacturing (volume of cans or pipes), and science (measuring liquids in graduated cylinders).
The Formulas
Volume = π × r² × h. Surface Area = 2 × π × r × (r + h). It treats the cylinder as a circular base extended through a height.
Fun Fact: If you unroll the side of a cylinder, it forms a perfect rectangle with a width equal to the circle's circumference (2πr)!
