Any one know how to get the midradius of a dodecahedron

For a dodecahedron with edge e the midradius can be calculated with

[unparseable or potentially dangerous latex formula]

where phi denotes the golden ratio.

In general, for the Platonic solids with Schäfli symbol [unparseable or potentially dangerous latex formula] and edge e, the midradius can be found with the formula
[unparseable or potentially dangerous latex formula]

Where h takes on values of 4, 6, 6, 10, and 10 for the tetrahedron, hexahedron, octahedron, dodecahedron, and icosahedron respectively.

The other two that I suggest you know are the circumradius and inradius. Theta denotes the dihedral angle.
