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.

Answer 1

a circle of radius r with center at (h,k) is

(x-h)^2 + (y-k)^2 = r^2

so, plug in your values.
radius is 160 ft
so, the center is at (0,9+160)

x^2 + (y-169)^2 = 160^2
