WebJun 15, 2024 · From the Pythagorean Theorem, the equation of a circle centered at the origin is x 2 + y 2 = r 2. The center does not always have to be on ( 0, 0). If it is not, then we label the center ( h, k). We would then use the Distance Formula to find the length of the radius. Figure 6.21. 2 r = ( x − h) 2 + ( y − k) 2 WebDec 27, 2024 · Know the equation of a circle. 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 …
