Answer to Problem 80RE
Explanation of Solution
Given information:
The figure shows below the specifications for an elliptical ceiling in a hall designed to be a whispering gallery. Where are the foci located in the hall?
Calculation:
Consider the given figure,
The height of the elliptical ceiling is
Width
Length of semi-major axis,
Length of semi-minor axis,
Foci lie at the points by coordinates
Assume that center of ellipse lies on the origin,
Now find eccentricity of the ellipse,
The foci of the ceiling lie at a distance of
Hence, the center is at a height of
