Okay first off, please don't flat out give me the answer cuz I want to do it myself. But I really just don't get how to do it!! So can someone please explain this to me?

Okay, so one, how do I draw the x^2 + y^2 = 10,000? Is it just a regular circle, the center at the origin, with an 100 meter radius?

And two, how do I find Quinn's coordinates on the graph? Once I get the circle set up, I'll be able to calculate his distance around the circle I'm sure, but how do I find the exact coordinates?

THANK YOU SO MUCH, if someone could answer within an hour or two I would be really appreciative, it is pretty urgent
