Arctic circle

Hi,
On a truely spherical earth the distance between the North Pole and the
Arctic Circle is equal to that between the Tropic of Cancer and the equator.
In reality both distances should be slightly different due to the flattening
of the Earth.
Does anyone know the exact numbers, based on current estimates for the
earth's diameter and flattening?
Thanks in advance,
