Imagine the center of the Orlando Eye is located at (0, 0) on a coordinate grid and the radius lies on the x-axis. Write an equation of a circle for the Orlando Eye.

The Orlando Eye is operated by Merlin Entertainments,[7] which also runs the world-famous London Eye. It's described as an observation wheel, because "[t]his is a stabilized-driven (capsule) that gives you a really smooth experience on the way around, so it doesn't feel like when you're at 400-feet, that you're swinging around in mid-air."[8] According to its official website, the Orlando Eye is the first wheel ever to use such a system in combination with a suspended ' ski lift capsule design'
