Draw it in the Sketcher and measure?

Let's say we have N wires around the core, outer diameter of bundle is D.

Assumed outer strands are all touching adjacent outer wire, plus touching inner "core" wire.

 

Let's say outer strands have diameter B, inner core is diameter C.

 

Geometry shows the following two equalities:

 

D = 2B + C

B = (C X SIN(180/N) / (1 - SIN(180/N))

 

For a given D, you can solve for C, which is algebraically not so tidy, but given by:

 

C = D / ((2 X SIN(180/N) / (1-SIN(180/N) + 1)

 

For your given example, this yields C = 0.0506, B = 0.0722
