Calculate the eccentricity of a shape

Formula

The formula to calculate the Eccentricity is:

\[ e = \frac{c}{a} \]

Where:

\(e\) is the eccentricity
\(c\) is the distance from the center to the focus point
\(a\) is the distance from the center to the vertex

What is Eccentricity?

Eccentricity is defined as the ratio of the distance from the center to a focus point to the distance from the center to the vertex. It is a measure of how much a conic section (such as an ellipse or hyperbola) deviates from being circular.

Example Calculation

Let's assume the following values:

Distance from Center to Focus (c) = 3 units
Distance from Center to Vertex (a) = 5 units

Using the formula to calculate the Eccentricity (e):

\[ e = \frac{3}{5} = 0.60 \]

The Eccentricity is 0.60.
