Step 2:

The details of the solution are as follows:

The equation of a circle is given as :


(x-a)^2+(y-b)^2=r^2

comparing with the given equation:


\text{( x+5)}^2+(y-4)^2=9

we have that:


\begin{gathered} \text{Centre ( a, b ) = ( -5, 4)} \\ and\text{ } \\ \text{Radius = }\sqrt[]{9}=\text{ 3} \end{gathered}

CONCLUSION:

From the detailed explanation, we can see that the correct answer is:
