Answer:
[tex](x+9.3)^2 +(y-4.1)^2 = 13[/tex]
How to solve it:
Given that the center of this circle is [tex]C=(-9.3, 4.1)[/tex] and the radius given is [tex]\sqrt{13}[/tex], the standard equation of a circle can be written like this:
[tex](x-(-9.3))^2 + (y-4.1)^2 = (\sqrt{13})[/tex]
This solves into: [tex](x+9.3)^2 +(y-4.1)^2 = 13[/tex]
