![]() ![]() So how can we figure that out? Well, we can set up a right triangle and essentially use the distance formula which comes from the Pythagorean Theorem. That line right over there, that is going to be the radius. So, for example, for example, this distance. To be the distance between the center and any point on the circle. And now, let's think about what the radius of the circle is. So, the x-coordinate is negative one and then the y-coordinate is one. And the center of theĬircle is just going to be the coordinates of that point. Alright, let's work through this together. I want you to pause the video and see if you can figure out Is a point that happens to sit on the circle. I guess, maroonish-red point right over here is theĬenter of the circle, and then this blue point So we have a circle here and they specified some points for us. ![]()
