Imagine drawing a circle, mark a single point inside that circle, then draw several lines going from the point to different points along the circle's circumference. (For the sake of variety, I'd ask that none of the drawn lines are parallel.) The equation would be designed to tell you the length of each of those lines. It may very well be possible to write the equation for calculating the length of a chord, which uses the circle's radius and the perpendicular distance of the chord from the circle's center:

c=2*sqrt(r^2-d^2)
