Can someone nudge me in the right direction to solving this problem?
I have a circle with a circular hole in it. I keed to find the diameter of the hole (d)
1. The circle diameter is D
2. The center coordinates of the hole is unknown
3. The hole can be anywhere within the circle
4. The hole is not in the center of the circle
Do you think it is possible to calculate the diameter of the hole by
creating two chords from a fixed coordinate on the circumference of
the circle that run tangental to, and on either side of the hole?
Would it be correct to suggest that
c1 + c2 <= 2D
Where c1 and c2 are the lengths of the two chords
D is the diamater of the circle
Am I on the right track? Where do I go from here?
Any help is appreciated.
