WebDec 27, 2024 · The standard form for the equation of a circle is (x – a)^2 + (y – b)^2 = r^2. The symbols a and b represent the center of the circle as a point on an axis, with a as the horizontal displacement and b as the vertical displacement. The symbol r represents the radius. [6] As an example, take the equation x^2 + y^2 = 16. 2 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 …
