Most people get it wrong because they ask a piss poor question relating to arc length.

I guess I am confused are you trying to find the radius of the top of this object? Is the object supposed to represent a cross section of something that has a concave top?

I am struggling to see how the radius can be greater then the 10cm base. I would think the answer would be 5cm.

Considering a 5/12/13 triangle with 13 being the Hypotenuse, 12 being the opposite side, and 5 being the adjacent side, would the radius not be 5.

Maybe I am missing something.

ETA: I think that I understand now, it is more like that radius of a sine wave, I believe.

"The top section does not have a radius, because it is not a circle. Only circles have radii. Next stupid question?"

Last sentence is mostly to establish dominance (always the #1 goal of an interview).

6 cm

ETA. OK. I've read through, and I believe your explanation of 13. Good solution.
