Solve.A Ferris wheel has a radius r of 26.8 feet. The height of the tower t is 36.6 feet. The distance d from the origin to the base is 22.5 feet. Find the standard form equation of the circle represented by the Ferris wheel.
A. (x + 22.5)2 + (y + 36.6)2 = 718.24 B. (x - 22.5)2 + (y - 36.6)2 = 26.8 C. (x + 22.5)2 + (y + 36.6)2 = 26.8 D. (x - 22.5)2 + (y - 36.6)2 = 718.24
