Equation for graphing a circle
WebWe're asked to graph the circle. And they give us this somewhat crazy looking equation. And then we could graph it right over here. And to graph a circle, you have to know where its center is, and you have to know what its radius is. So let me see if I can change that. And you have to know what its radius is. WebJun 15, 2024 · Graph a circle. Use ( h, k) as the center and a point on the circle. Formula: ( x − h) 2 + ( y − k) 2 = r 2 where ( h, k) is the center and r is the radius. Recall that a circle is the set of all points in a plane that are the same distance from the center. This definition can be used to find an equation of a circle in the coordinate plane.
