Hello
Please could anyone explain this to me :
for the equation of circle :
(x-h)^2 + (y-k)^2 = r^2
I don't understand why the centre of the circle is at the point (h,k) ?
e.g
if (x-2)^2 + (y-k)^2 = 36
(8,0) is a point on the circle ,but 8 is obviously longer than the radius which is 6 ?
Thanks for any help
Roger
