Hollow Cylinder Calculator
Calculate the material volume of a hollow cylinder or pipe.
How to Use the Hollow Cylinder Calculator
Enter the outer radius, inner radius and cylinder length to calculate the material volume in a hollow cylindrical shell.
Practical Example
For outer radius 5, inner radius 3 and length 10, the material volume is about 502.65 cubic units.
Factors That Affect the Result
The inner radius must be smaller than the outer radius. Use consistent units and confirm whether dimensions are radii or diameters.
Frequently Asked Questions
What does hollow-cylinder volume represent?
The volume of material between the outer and inner cylindrical surfaces.
Can the inner radius equal the outer radius?
That would produce zero material volume.
What units are returned?
Cubic units.

Understanding Hollow Cylinder Volume
A hollow cylinder’s material volume is the difference between an outer cylinder and an inner cylinder: πh(R² − r²). This is useful for pipes, sleeves and tubular parts.
Outer radius, inner radius and length must use the same unit, and the inner radius must be smaller than the outer radius. If diameters are measured, divide them by two first. For real parts, tolerances and non-uniform wall thickness can make actual material volume differ slightly from the ideal geometric result.
