i have a doubt on ELLIPSE. Say i have two points of my ELLIPSE, ie major axis as "2a", and minor axis as "2b". if i cut the ELLIPSE into TWO parts on Major axis. then i will have two ARCS(or some curve). My problem is to find the CENTRE of the Circle which is forming this ARC (curve).

my other problem is

say i have radius of the above curve as (r) . when i increase the height of the curve my radius shifts from it's position. is the resultant radius equal to the (increased height+ r). ie, r= increased height+ r ?

please reply to my questions. Thanking you in advance.
