We have this take home quiz and there is one part I don't understand, in the quiz he tells us to "determine the equation of a circle with a center at (-2,3) and passing though the origin" but he doesn't give us the radius. I have no idea how to solve this, I mean I got completely lost after (x-(-2))^2 + (y-3)^2 = r^2
