What is the definition of metallic radius?

Aren't all kinds of radii defined as half the distance from the center of 1 atom to the center of the next adjacent atom? regardless of whether it's a covalent/ ionic bond or just sitting there as a metal

Not necessarily, as far as I know, but this is a good start for metals. So, the radius of some shape is 186 pm. What shape (roughly) are atoms?

Sphere..
So this is just 4/3(pie)(186)^3 I guess? Thanks

Sounds sensible, bear in mind units and significant figures
