<PRE><B>Question 514290</B>
A ferris wheel has a diameter of 320 feet and the bottom of the Ferris wheel is 9 feet above the ground. Find the equation of the wheel if the origin is placed on the ground directly below the center of the wheel, as illustrated.
---
radius = 160
center is at (0,169)
----
Equation:
x^2 + (y-169)^2 = 160^2
