Well, I'm assuming that we know the coordinates of the two points-- in which
case, you'll get slightly different results on the baseball and the
basketball... Using the 1 inch string on the basketball will create two points
which are further apart (in actual space, not along the circumference) than
when you use the string on the baseball... However, after looking at what he's
asking, that's not at all what he meant. I'm looking at it in a completely
math oriented world where we know x1,y1,x2,y2, and the minimal distance along
the circumference of the circle L between the two points. Hence, we actually
can calculate the "real" distance between the two points completely without L.
The distance between the points is easily calculatable with just x1,y1,x2, and
y2.
