Did you know?
WebbThe equation of a circle in general form is, x 2 + y 2 + Dx +Ey + F = 0 where D, E, and F are real numbers. To more easily identify the center and radius of a circle given in general form, we can convert the equation to standard form. Example: Find the center and radius for the circle with equation, x 2 + y 2 + 4x - 12y - 9 = 0 WebbThat is, the exercise will not explicitly state that you need to use the Distance Formula; instead, you have to notice that you need to find the distance, and then remember (and apply) the Formula. For instance: Find the radius of a circle, given that the center is at (2, −3) and the point (−1, −2) lies on the circle.
