Situation: Whispering Gallery
As a result of their unique elliptical shapes, whispering galleries enable the smallest sound generated at one
focus to be carried across the room to the other focus. The whispering gallery at the Chicago Museum of
Science and Industry is 47 ft 4 in long and 14 ft 6 in wide.

Situation: Orbit of Venus
The orbit of Venus is nearly circular. An astronomer develops a model for the orbit in which the Sun has
coordinates (-5, 20), the circular orbit of Venus passes through (62, 20), and each unit of the coordinate plane
represents 1 million miles.
Graph and Math
Equation of the circle is (x+5)squared + (y-20)squared
Venus is 67 million miles away from the sun
It takes Venus 1,4095.46 million miles to orbit around the sun
