Immediately. But the area ratio decreases slowly at first then more rapidly. The area of an ellipse is A=pi x a X b, a and b are the 1/2 major and 1/2 minor axis. If a = r = b the area is A=pi X r2 , which is a circle. Not hard to graph this....but you will have to write the area of the ellipse in terms of the circumference. There is no exact formula for this-- see: http://home.att.net/~numericana/answer/ellipse.htm#elliptic

An ellipse is a closed curved shape that resembles a squashed circle. It has two distinct points called foci, and the sum of the distances from any point on the ellipse to the two foci is constant. The major axis is the longest diameter of the ellipse, while the minor axis is the shortest diameter.
It is the center of the circle
The point from which the circle is drawn IS the center.
A circle has a round shape in which every point on the circle is the same distance from one point called "the center". The center of a circle is not on the circle.
That point is known as the "center of the circle". Every circle has one.
