Question

Find the equation of the circle when given:
3 point on the circle: (-7, 6), (9, 6), and (-4, 13)

Answer 1

one approach is to plot the points to "see" better
apply pythagorean theorem
equation of the circle (x-h)^2 + (y-k)^2 = r^2 where center is (h, k) and the radius is r

you have 3 points on the circle the center to any point is the same distance, r
