Can I enter diameter?
Yes. The tool converts diameter to radius before applying the formula.
MAXScanner calculator
Cylinder Volume Calculator — Volume, Surface Area & Fill
Calculate solid cylinder volume, lateral area, total surface area and optional filled volume from radius or diameter and height.
Result
1.5708 cubic units
6.28319 lateral area · 7.85398 total surface area
1.5708 cubic units at 100% fill
Formula and worked example
V=πr²h; lateral area=2πrh; total area=2πr(r+h); filled volume=V×fill%.
Radius 0.5 m and height 2 m gives volume π×0.25×2 ≈ 1.5708 m³.
Assumptions
- Right circular cylinder geometry.
- Dimensions use one consistent length unit.

Frequently asked questions
Does fill percent model a horizontal tank?
No. Fill percent is a simple fraction of full volume, appropriate to a vertical cylinder model.
