Answer 1

Step 1:

In this question, we are given the following:

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:

`(-5,\text{ 4); r = 3 ( OPTION }C)`
