The center of a circle is located at (3, 8), and the circle has a radius that is 5 units long. What is the general form of the equation for the circle?
First we write equation that consist coordinates of center and radius. That formula goes like this: (x-x1)^2 + (y-y1)^2 = r^2
x and y are coordinates on any point on circle x1 and y1 are coordinates of center of circle. r is radius of that circle. now we need to express our values for center and radius andf square binoms and see what matches in our options.
