eccentricity (x^2)/(8^2)+(y^2)/(4^2)=1

eccentricity

\frac{3}{2}

Decimal

0.86602 \dots

Solution steps

= \frac{a ^{2} - b ^{2}}{a}

Calculate ellipse properties

\frac{x ^{2}}{8 ^{2}} + \frac{y ^{2}}{4 ^{2}} = 1 :

Ellipse with center

(h, k) = (0, 0), a = 8, b = 4

= \frac{8 ^{2} - 4 ^{2}}{8}

\frac{8 ^{2} - 4 ^{2}}{8} = \frac{3}{2}

= \frac{3}{2}
