Given the Center & a Point Find the Equation of a Circle

When we are given the center and radius of a circle, it is super easy to plug those into the standard form of a circle to get the equation. But, sometimes, we aren't given that information, but we are given ways to find that information. In this example, we are given the center point and a point on the circle. Using these two points, we can use the distance formula to find how far apart they are. Guess what, that's our radius!
