radius(obj)
obj
-
geometric object
If obj is a sphere, radius(obj) returns the radius of obj.
If obj is a regular polyhedron or an archimedean solid, radius(obj) returns the radius of the circum-sphere which passes through all the vertices.
If obj is a dual of an archimedean solid, radius(obj) returns the radius of the in-sphere which touches all the faces.
The command with(geom3d,radius) allows the use of the abbreviated form of this command.
