If possible find the radius of a circle that has chord length 176cm's.

Question

anonymous · Answer

you still there, need help?

anonymous · Answer

do you know the height of the arc created by the chord?

trancenova · Answer

hey, yeah still trying to work it out. essentially I have a sheet of paper with two points and i'm trying to work out how to draw a circle that will go exactly through those two points

anonymous · Answer

but do you have the heigt

anonymous · Answer

*height

trancenova · Answer

lol no, just two dots on a page (I suspect this may not be possible)

anonymous · Answer

look like it, b/c if you had the height, coupled with the fact that you have been given the lenght, we could easily compute the radius.

trancenova · Answer

Yeah I know, this is why its driving me nuts, I suspect if I use my compass I can somehow do it, though I haven't quite worked it out yet

anonymous · Answer

when you figure it out, come back casue i am curiouse to know the answer

trancenova · Answer

Yay! I got it, it was annoyingly simple. First I made my compass the length of the chord (176) then I put my compass on one end and drew part of the circle above the chord and then did that on the other end of the chord. This gave me a point where they intersected. I used that intersect point as my circle center and drew... this makes the radius 176 (diagram attached).
