Question

If the distance between the foci of an ellipse is 6 and the length of the minor axis is 8, then the eccentricity Is

• A. $\frac{1}{\sqrt{5}}$
• B. $\frac{1}{2}$
• C. $\frac{3}{5}$
• D. $\frac{4}{5}$

Answer 1

The correct option is C

$\frac{3}{5}$

$2ae=62b=8$

$a^2=b^2(1-e^2)\Rightarrow a=5\Rightarrow e=\frac{3}{5}$
