Question and answer
Q: What is one relationship between lines and circles? Explain at least one real-world application of the relationship.
A: Assuming that you have the radius of the circle: r The straight line distance between 2 pts on the circle : c The curved distance between the same two pts : s You can compute s from r and c using: s = r 2 arcsin (c / 2r ) You can compute c from r [ and s using: c = 2 r sin(s / 2 r) Note: in this case the trig functions are operating on angles measured in radians. see also : ]
