Am I unsuccessful because the material on the outside edge would have to travel faster then light or am I successful because length contraction at the outside edge reduces the circumference?

At any given time is a point on the edge traveling twice as fast or less then twice as fast as a point 50,000 km from the center?

Is the geometry of a rotating object inherently non Euclidean?

I think that's 3 different ways of asking the same question. If not I'm particularly interested in what the difference is?
