Dear DeDackel, Remy and Chris Tietjen,

Thank you so much, but I did a stupid thing that I didn't make it clearly that the surface of the arc should be vertical (comparing with your advices which are horizontal) on the circal as you created. the whole thing would look like a divided half sphere.

Hi Yulia,

It may be that one of the two points of the arc, do not be on it.
There are several approaches to the problem. Be the math, be may be this one.
