So I had a student today ask me if I could come up with a simple 2 dimensional area problem. I was like -sure what is it. The question was:(adsbygoogle = window.adsbygoogle || []).push({});

If a cow were strapped to a tether outside a 10' by 10' square barn, at the corner of a small outlet door, and had a 100' leash/tether, what would the area be that he could cover to graze?

So the obvious is a circular sweep CCW with a 100 square foot keep out area in one direction, but then other? any ideas how to compute this one? thanks newbie
