Formula
V = πr²h | Lateral = 2πrh | Total = 2πr(r+h)
Example
r = 25 mm, h = 80 mm → V = 157 080 mm³ ≈ 0.157 L, total surface = 16 493 mm².
FAQ
How do I find cylinder volume in liters?
Compute πr²h in mm³ and divide by 1 000 000 (or work in cm and divide cm³ by 1000).
What is the lateral area used for?
It is the wall area of the cylinder — used for labels, sheet-metal development and painting estimates.
