The equation of the circle is given as

How to get the equation
Given that the center of the circle is 1, we can substitute these values into the formula to find the equation of the circle:
The equation is in the standard form for the equation of a circle, which is given as :

Given that the center of the circle is (−1,−4) and the radius is 1, we can substitute these values into the formula to find the equation of the circle:

Then we have to expand this which would give us
