Equations for a circle

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. WebGiven a circle with radius, r, centered at point (h, k), we can use the distance formula to find that: where (x, y) is any point on the circle. Squaring both sides of the equation, we get the equation of the circle: …
