Solve.A Ferris wheel has a radius r of 25.8 feet. The height of the tower t is 35.5 feet. The distance d from the origin to the base is 32.6 feet. Find the standard form equation of the circle represented by the Ferris wheel. 

A. (x + 32.6)2 + (y + 35.5)2 = 25.8 B. (x - 32.6)2 + (y - 35.5)2 = 665.64 C. (x + 32.6)2 + (y + 35.5)2 = 665.64 D. (x - 32.6)2 + (y - 35.5)2 = 25.8
