Answer: 
Step-by-step explanation:
Given: The diameter of the Ferris wheel= 100 feet
therefore, the radius of the Ferris wheel= 50 feet
Also, the highest point of the wheel is 125 feet.
Since , y axis represents the center of the wheel.
The center of the wheel= (0,125)
The equation of circle with center (h,k) and radius 'r' is given by :

Thus, the equation of the circle with center (0,125) and radius=50 is given by :-

1/18 would be your answer because 3 * 6 = 18. so 18 is your denominator. 1 * 1 is still 1 so that would be your numerator. You cant simplify the numerator because it's a one and can't be simplified by any other number but 18 can be simplified but it wouldn't make sense to just simplify the denominator and not the numerator so It would stay as 1/18.
