Thank you, Hoppy.  Now we know all the emojis work. 

i found no difficulty in researching tropic of cancer diameter but the tropic of capricorn does not have a reported diameter

The references I found only listed the circumferences of the tropic of cancer and the tropic of capricorn.

The circumferences of the tropic of cancer and the tropic of capricorn  are approximately equal, so their diameters would also be approximately equal.

If the Azimuthal Equidistant Projection, which seems to be the only "flat earth map"  that the FES has at present, was used,  the tropic of capricorn would be much larger in circumference than the tropic of cancer,  and therefor also the  diameter.
