Ok... the warning .... quit using folders and filenames with spaces in them... just don't, even if they work sometime, they will bite you... old school will leap in I hope to support this notion.
now. your cell size and radius... why chosen? why a circle? what does it say in the help? what happens when you vary these parameters? Don't try to emulate an example unless you know that your data and conditions enable you to reproduce the same outcomes. You got what you got because that is what you used. If you check the parameters there is lots you have to understand, since each parameter variation will produce a different output.
Since this seems to be an assignment or a final project, it is your turn to justify what you chose and why.. Just because it is a default... if that is the case ... certainly doesn't make it right or even good.
Good luck
