So, I have run into a problem with an assignment, which, for many of you on here, is not really a problem at all. Below I have attached a picture of said assignment. It would be greatly appreciated, if someone could tell me, which commands are to be used to achieve the pictured result. I thank you in advance. 

The eight circular hatch patterns could be replicated using the ARRAY command.  All you need is just one to get the process started.The three smaller circular patterns look to me as though a single large circular pattern was copied, rotated, overlaid on another one then scaled down.  Finally it too could be arrayed in a single row.Without testing my theory I can't be 100% sure.  Maybe later when I have some spare time I can fire up my CAD computer and see what I can come up with.

Commands used could be...CircleLineOffsetCopyArrayScale...and a couple of miscellaneous ones depending on how you might approach the exercise and your skill level.Utilizing osnaps might come in handy too.

Just for fun I used decimal inches. 

After removing most of the circles.  BTW...the hatch pattern I had in mind originally would have been a gradient but AutoCAD doesn't have one with just lines.
