Using the center point and the radius, you can **find** the **equation** of the **circle** using the general **circle** formula (x-h)*(x-h) + (y-k)*(y-k) = r*r, where (h,k) is the center of your **circle** and r is the radius. Now substitute these values in that **equation**.

The standard form equation of a circle is a **way to express the definition of a circle on the coordinate plane**. On the coordinate plane, the formula becomes **$$**(x -h)^2 + (y - k)^2 =r^2 $$. h and k are the x and y coordinates of the center of the circle.

To find the midpoint, or center, of a circle, follow these instructions: Find two points on the circle that are completely opposite from each other, i.e., that is they are separated by the diameter of the circle. If you know their coordinates, add the two x coordinates together, and divide the result by 2. ... Do the same for the 2 y coordinates, which will give you the y coordinate. More items...
