VolLab
Radius × radius × height × π — plus surface area.
A cylinder's volume is just its circular cross-section (πr²) stacked up over the height — the same logic as a rectangular box's volume being its footprint times height.
Cans, pipes, water tanks, and cylindrical containers of every kind rely on this formula to determine capacity or the material needed to build them.
