#### Explanation:

The general form of a circle:

where

Since the center of the circle is

Now, all we need to know is the radius length, which we can find by applying to distance formula with the circle's center and another point on the circle:

Thus, the radius is

Thus, the equation of the circle is:

graph{(x-1)^2+y^2=18 [-10, 10, -5, 5]}
