| Dec 15, 2017 at 15:17 | comment | added | Gerhard Paseman | Looking at the shapes of two, three, and four circles may be informative. Pentagon distance would be a good approximation: roll along an optimal angle to achieve y distance, then go along x to hit point. My guess is Pentagon distance and roll distance will differ by at most one. Gerhard "Try Drawing A Five Sphere" Paseman, 2017.12.15. | |
