Question

Determine the equation of the circle whose endpoints of a diameter of a circle are (-6, 2) and (6, -2)

Answer 1

you can find mid point of diameter which is center of the circle after that distance between mid point and one midpoint is the radius now put his values in the formula (x-a)^2 - (y-b)^2 =r^2 where (a,b) coordinate of midpoint and r is radius.
