Solve the problem using a graphing calculator.A Ferris wheel with a radius of 38 feet turns clockwise at the rate of one revolution every  The lowest point of the Ferris wheel is 18 feet above ground level at the point (0, 18) on a rectangular coordinate system. Find parametric equations for the position of a person on the Ferris wheel as a function of time (in seconds) if the Ferris wheel starts (t = 0) with the person at the point 

A. x = 38 cos (20t)° ft, y = 38 sin (20t)° + 56 ft B. x = 38 cos (20t)° ft, y = 38 sin (20t)° + 18 ft C. x = 38 cos (18t)° ft, y = 38 sin (18t)° + 18 ft D. x = 38 sin (20t)° ft, y = 38 cos (20t)° + 56 ft
