This is a riddle for people who are really good a math.. please try, and see if you can get it!?

Question

Assume the world of Neopia is a spherical planet with a diameter of 1600 km with a uniform density of 5200 kilograms per cubic metre. If the moon of Kreludor is in a geostationary orbit around Neopia, and assuming a Neopian sidereal day is exactly 24 hours, how far is that geostationary orbit above the surface of Neopia?

Answer 1

41,270 km.

(I think the point of the original source is for *you* to work it out, not post endless copies in a forum like this)

Answer 2

Do you know how many times this has been posted? (>30, certainly).

Why not search for the question before posting it...

ADDED: and its not a riddle - its a math question.

A riddle would suggest something that is a bit freaky - this is a simple matter of basic algebra and equating gravitational and centripetal forces - how is that a riddle?
