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 bottomOpen 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 = 2⋅π⋅(r^2−(r−t)^2)+2⋅π⋅r⋅h+2⋅π⋅(r−t)⋅h`

where:

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