+267 Find the coordinates of the center of the circle.
The points on the circle are (22,15), (-25,0), (22,-29).
+37147 Each of these points is the same radius distance from the center to the point.....using distance formual for the first two points
(x-22)^2 + (y-15)^2 = ( x+25)^2 + (y-0)^2 reduces to
-94x - 30y + 84 = 0
For the last two points:
(x+25)^2 + y^2 = ( x-22)^2 + ( y+29)^2 reduces to
94x-58y-700 = 0
Add the two reduced equations to get
-88y = 616
y = -7
Now put this valueof 'y' into either of the reduced equations to find
x = 3.12765
Center = ( 3.12765, -7)
