Converting from average mean radius (AMR) to extreme spread gives value for 10 shot groups for or 1.94 Minute of arc.

The requirement is a pair of close-wound coils, mounted on the same axis and separated by a mean distance equal to their mean radius, as shown in Fig. 12.

Many jet engines have a short annular passageway, linking two components, where there is a large change in mean radius, from front to rear.

The most prominent Kirkwood gaps are located at mean orbital radii of:

It has a mean radius about three times the radius of the Sun.

In some situations sea level does not apply at all - for instance for mapping Mars' surface - forcing the use of a different "zero elevation", such as mean radius.

The Moon's mass is 0.01230 M E and its mean radius is 1737 km.

It is also common to refer to any mean radius of a spherical model as "the radius of the earth".

Also, it should be possible to compute families of curves giving possible relationships between planet-to-satellite mass ratios against mean orbital radii.

The effective potential in the solution of motion in a magnetic or electric system with rotational symmetry leads to radial focusing onto a mean radius.
