Use the Following Information to Solve the Problem $( x + 43.9 ) ^ { 2 } + ( y + 49.7 ) ^ { 2 } = 25.8$

Use the following information to solve the problem. An airport is located at point O. A short-range radar tower is located
at point R. The maximum range at which the radar can detect a plane is 4 miles from point R.
-A Ferris wheel has a radius r of 25.8 feet. The height of the tower t is 49.7 feet. The distance d from the origin to the base is 43.9 feet. Find the standard form equation of the circle represented by the Ferris wheel.

A) $( x + 43.9 ) ^ { 2 } + ( y + 49.7 ) ^ { 2 } = 25.8$
B) $( x + 43.9 ) ^ { 2 } + ( y + 49.7 ) ^ { 2 } = 665.64$
C) $( x - 43.9 ) ^ { 2 } + ( y - 49.7 ) ^ { 2 } = 25.8$
D) $( x - 43.9 ) ^ { 2 } + ( y - 49.7 ) ^ { 2 } = 665.64$
