The Surface Area of a Hollow Cylinder calculator computes the surface area of a hollow cylinder based on the dimensions.  This is for an open ended cylinder with no top or bottom/attachments/0ae28e4b-3fa9-11e9-8682-bc764e2038f2/Cylinder - Hollow.pngOpen Ended (no top or bottom) and represents the surface area of the rimmed edges and the inner and outer surfaces of a hollow cylinder.

INSTRUCTIONS: Choose units and enter the following:

  • (r) Outer radius of the cylinder.
  • (h) Height of the cylinder.
  • (t) Thickness of the cylinder wall.

Hollow Cylinder Surface Area (SA): The calculator computes the surface area in square centimeters.  However this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the surface area of a hollow cylinder is:

         SA=2π

where:

  • SA = surface area of the cylinder
  • h = height or length of the cylinder
  • r = outer radius
  • t = thickness
