Find an equation of the circle whose diameter has endpoints (2,2) and (-6,5) .

(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

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

other answer is correct. i had used the radius of the radius somehow. a website:
