Hollow Cylinder (Pipe) Volume Calculator

Find the volume, wall thickness, and surface area of a hollow cylinder (pipe) from its outer radius, inner radius, and height.

Input

Enter the outer radius R, inner radius r, and height h to calculate the volume of a hollow cylinder (pipe).

Outer radius R

Inner radius r

Height h

Volume

628.318531

Wall thickness

Surface area

753.982237

Lengths use the same unit as the inputs. Volume is in cubic units and area in square units.

The volume is V = π(R² − r²)h, where R is the outer radius, r is the inner radius, and h is the height.
The wall thickness is t = R − r, the outer radius minus the inner radius.
The surface area is the outer wall 2πRh plus the inner wall 2πrh plus the two end rings 2π(R² − r²).
The inner radius must be smaller than the outer radius. Use the same length unit for all inputs, so volume is in cubic units and area in square units.
