Center of Mass Question

[CNBA3]

I have a question as to how one gets an answer with the final formula on the late G[http:// https://vsbattles.fandom.com/wiki/User:Gwynbleiddd wynbleiddd's] Blog with Center of Mass :

• $ W=Gm^2(1/ri-1/rf) $

I tried doing the formula to see if I can get the same answer as he did but I get answers like this (0.00403125864) I do not know If there is anything more to it, but I am certain I have applied all the right inputs in each area.

Can anyone help?
