  There's no solution. Not finite one, that is.

  If you try to calculate it, you probably get a division by 0 or another
similar undefined result.

  Geometrically this is explained by thinking that the only solution is
a circle with infinite radius and the center being at infinity. That is,
the circumference is a straight line.
