Question

A plot of land in the shape of a vertical ellipse has a pole at each focus. The foci are 8 feet from the center.
If the plot of land is 34 feet across the vertical axis, then it is (24, 30, 32, 36) feet across the other axis.

The eccentricity of the ellipse traced by the boundary of this plot, rounded to the nearest thousandth, is (0.543, 0.515, 0.471, 0.459).

Answer 1

Please help!?

Answer 2

sorry this took so long but

"foci are 8 feet from the center" implies c = 8
this is a vertical ellipse so a will be half the length of the vertical axis, so 2a = 34 making a = 17

solve for b, then double it to get the length of the other axis

then for eccentricity simply calculate c/a
