Answer: The center of the circle is at the point (-21,-19), and its radius is units.
The standard form of circle:
Step-by-step explanation:
The given the equation of circle :-
The general equation of circle is given by :
Here, the center of circle= (-h,-g)
and radius =
Now, Comparing the given equation to the general equation, we get
Thus, the center of the given circle= (-21,-19)
Radius of given circle =
Now, the standard form of circle will be
