WebTo find the equation for a circle in the coordinate plane that is not centered at the origin, we use the distance formula. This method can also be used to find the equation for a circle centered at the origin, but in such a case, using the equation in the previous section would be more efficient. ... Find the center and radius for the circle ... WebIt's just the distance from the center out to the edge. If that radius is 3 centimeters, then this radius is going to be 3 centimeters. And this radius is going to be 3 centimeters. It's never going to change. By definition, a circle is all of the points that are equal distant from the center point. And that distance is the radius.
WebYou know the equation of a circle has the form $$ r^2=(x-a)^2+(y-b)^2. $$ If you have the equation in this form, you can read off the center and radius. But you don't have that. You need to do a bit of work to get what you have into the form you want. The tool to use here is: Completing the Square WebPractice Questions on Equation of Circle.
