The eccentricity of an ellipse is a measure of how nearly circular the
ellipse is, and is found by the following formula:
<blockquote>
eccentricity = c/a

<blockquote>
c = distance from the center C to focus F, and

<blockquote>
a= distance from the center C to vertex V.<br />

In the given diagram, visualize a horizontal line through F1 and
F2. Then, we have,

<blockquote>
< c >
</blockquote>
<blockquote>
< a >

<blockquote>
Since c > 0.5a and c < a, the approximate eccentricity is c/a
= 0.7 <br />
