Cylinder
Calculates volume V = πr²h and surface area from radius r and height h.
Volume

Lateral surface
62,83
Total surface
87,96

Formula
V = πr²h; lateral = 2πrh; total = 2πr(h + r)
Example: r = 2, h = 5 → V ≈ 62.83
Methodology
Volume V = πr²h. Surface S = 2πr² + 2πrh.
Example
r = 2 cm, h = 10 cm: V ≈ 125.7 cm³.
