nope, you can't break it ... you have to walk 1km north THEN 1km west and THEN 1km sourth. Also, if you think there are infinitely many such places, can you described them (e.g. how to find them)
Originally posted by Mephisto2quite close, actually i think you just forgot to devide by pi ... so
1 = southhpole
every point on every parallel near the north pole with a perimeter of 1/1, 1/2, 1/3, ... km
Originally posted by 3v1l5w1nWhy would I have to divide the perimeter by pi to find the perimeter?
quite close, actually i think you just forgot to devide by pi ... so
all the solutions can be described as this:
1.) the South Pole
2.) the union of concentric circles with the center at the North Pole and the radius r = ( 1 / 2 * pi * n ) + 1 where n is 1, 2, 3, ...
