Given:

There is a equation of circle given in the question as below

[tex]\left(x+7\right)^2+(y-1)^2=9[/tex]

Required:

We want to find the center and radius of given circle

Explanation:

The general equation of circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]

where (h,k) is the center of circle and r be the radius of circle

Now by comparing we get

[tex]\begin{gathered} (h,k)=(-7,1) \\ r^2=9\Rightarrow r=3 \end{gathered}[/tex]

Final answer:

C
