Find the equation of the circle which passes through the points `(2, 8), (5, 7) and (6, 6)`.

Explanation

To find the equation of the circle that passes through the points (2, 8), (5, 7), and (6, 6), we can follow these steps:

### Step 1: Set up the general equation of a circle
The general equation of a circle is given by:
\[ (x - h)^2 + (y - k)^2 = r^2 \]
where \((h, k)\) is the center of the circle and \(r\) is the radius.
