Webquestions. Lately, I have been researching different shapes and their equations. For instance, the equation, x2 +y2 = 1, generates a circle centered at the origin with radius 1 unit. While my textbook provides equations for conic sections—ellipses (including circles), hyperbolas, and parabolas—the WebThis means that, using Pythagoras’ theorem, the equation of a circle with radius r and centre (0, 0) is given by the formula \ (x^2 + y^2 = r^2\). Example Find the equation of a …
