# Circles Outside a Circle

## Calculate the numbers of circles on the outside of an inner circle - like the geometry of rollers on a shaft.

The calculator below can be used to calculate the maximum numbers of rollers on a shaft - or - the maximum number of circles on the outside of an inner circle.

The calculator is generic and any kind of units can be used - as long as the same units are used for all values.
