Instantly calculate cylinder volume using radius, diameter, or circumference. Supports both solid and hollow cylinders.
Schematic representation • Not to scale
The calculation relies on the geometric properties of a cylinder. Whether solid or hollow, the core principle is derived from the area of the circular base multiplied by the height (Cavalieri's principle).
V = π · r² · h
Where r is radius and h is height.
V = π · (R² - r²) · h
Where R is outer radius and r is inner radius.
