Answer:
(x + 2)² + (y - 3.5)² = 18.25
Step-by-step explanation:
diameter has endpoints (2,2) and (-6,5), center (h,k) = ((2 + -6)/2 , (2+5) / 2))
center (h,k): (-2 , 3.5)
diameter = √(-6-2)² + (5-2)² = √73
radius = √73/2
equation: (x - -2)² + (y - 3.5)² = (√73/2)² = 73/4
(x + 2)² + (y - 3.5)² = 18.25
