Write the standard form of the equation of a circle that passes through the points at (0,8) (8,0) and (16,8). Then identify the center and radius of the circle.
(x8)^2 + (y8)^2 = 64
(x^2 / 64) + (y^2 / 64) = 64
center=(8,8)
radius=8
I got it wrong don't know how

(x8)^2 + (y8)^2 = 64
fine
(x^2 / 64) + (y^2 / 64) = 64
but where did you get this??????
center=(8,8)
fine
radius=8
fine

You will have to write the equation
(xh)^2+(yk)^2=r^2
for the three sets of points given. Then solve for h, k, r
It is ugly but solvable.
