i need some help

well i have afew home work problems and dont kno them and if i dont get these rite i have theposibility of failing and i have no ware to look
problems:
1) if a circle has a circumfrance of 24 pie (or 24 in terms of pie) then what is its radius?
i think it is 12 but im not sure???
2)i have to scetch a graph for these points or i guess you would call these points:
(x+2)squared+y squared=4
and another graph with this point:
(x-3)squared+(y+1)squared=9

3) an open response question that said something about a something that picks up distince to an "earth quake" but not direction to it and it gives you 3 cordinates=
(-3,5) and 5 miles away
(-3,3) and 3 miles away
(4,0) and 7 miles away
these are all dealing with circles

I'm too many years away from the first question and my brain doesn't want to remember.

the second sounds like you are refering to triangulation. Use those points to swing an arc or circle towards a point where all three radius intersect at some point between the three original points. This should give you the epicenter of the quake.

OH !!!OH !!! I GOT IT !!!! Let me try to reexplain the second one. With a compass, Use -3,5 as a point and swing a radius 5 miles from it. Use -3,3 and swing a radius 3 miles from it. Use 4,0 and swing a radius 7 miles away. Somewhere between the three original points, the three circles intersect. That is your epicenter.

You understand why I'm a business man and not a teacher? Does what I said make any sense or did I loose you. I did these in geology classes frequently.

u kinda lost me
so on a graph (like a + shaped graph) what cordinates would i plot?
and for how many miles away that would represent the radius
ok im starting to understand it
so you take the three cordinates or two(?) and plot them and draw th radi and where they all intersect is where the "earth quake"is? correct???
