Eccentricity is found by the following formula
eccentricity = c/a

Practice Problems
A circle is a special case of an ellipse. Analogous to the fact that a square is a kind of rectangle, a circle is a special case of an ellipse. In terms of the eccentricty, a circle is an ellipse in which the eccentricty is zero.
