Calculate the volume and surface area of a shell use this cylindrical shell calculator. Enter the inner radius, out radius, and length of the shell into the calculator below.

## Cylindrical Shell Formula

The following formulas are used int he cylindrical shell calculator above. The first formula is used to calculate the volume.

V = (R^2 – r^2) * L * PI

- Where V is volume
- R is the outer radius
- r is the inner radius
- L is the length/height

The following formula can be used to calculate the total surface area of a shell:

A = 2*PI*(R+r)*(R-r+L)

- Where A is the surface area
- r is the inner radius
- R is the outer radius
- L is the height
