kindergarten circles project

I need to cut out 200 circles out of regular 8 1/2 by 11 paper.  If each radius must be 1 inch long,  what is the fewest amount of sheets needed? Assume I can use tape.

If you can use tape, does it mean you can make circles from an arbitrary number of pieces?
 
I would cut the paper in narrow stripes and stick them together into circles.
 
That's probably not what you meant.

That is exactly what I meant.  My students tend to focus on circles as disc and not consider them as ribbons.  So of course it can be fine with 1 sheet.

so it boils down to an area calculation problem?  In that case the answer is:
7 sheets. But you'll probably need a lot of tape and patience
 
PS: What is the smallest number of sheets needed if you have no tape?

I think it can be done with 20 sheets.
