Default Re: Math Equation for you all

If I graph the circle with center, (0,-294), and then graph, "y=4, y=8, y=12... y=80" I can just find the intersections of the lines and the circle, and that will be the lengths correct?
What is the equation of a circle again in Y= form?... (x-h)^2 + (y-k)^2 = r^2
So... x^2 + (y + 294)^2 = 294^2

x^2 + y^2 + 588y + 86436 = 86436
- 86436 -86436
x^2 + y^2 + 588y = 0

Anyone want to help me from here? I know... basic algebra 2, but I'm not sure if I am doing right so far....
