Question

A Ferris wheel has a maximum height of 245 feet and a wheel diameter of 230 feet. Find an equation for the wheel if the center of the wheel is on the​ y-axis and y represents the height above the ground.

equation is ?

Answer 1

radius must be 115 ft
and its center must be 245-115 or 130 above the x-axis, (the ground)

equation:
x^2 + (y-130)^2 = 115^2 = 13225

Answer 2

A Ferris wheel has a maximum height of 270 feet and a wheel diameter of 250 feet. Find an equation for the wheel if the center of the wheel is on the​ y-axis and y represents the height above the ground.

Answer 3

x^2 + (y-145)^2=15625
