Standard Form of a Circle - Effortless Math

WebJan 8, 2024 · In this video you will learn everything about the equation of circle. WebThe standard equation of a circle is (x-h)^2+ (y-k)^2=r^2, where (h,k) is the center. The equation Sal started with was not in this format. Thus, in order to be able to graph the circle, he needed to change the appearance of the equation. We don't change the equation itself, though; we don't change any values. WebFrom the standard form of a circle, we have k = -1 * +5 = -5 Determine center of the circle: Therefore, our circle has a center (h, k) = (2, -5) Determine radius: Therefore, we have r 2 = 81 r = ±√ 81 Since a radius is always positive, we have r = 9 Determine the general form of the circle equation given center ( h, k) = ( -2, +5) and radius r = 9: park hill group hedge fund
