Answer:
FIRST option is the correct answer
Step-by-step explanation:
First option is the correct answer.
[tex] (x+11)^2 + (y+ 6)^2 = 324\\
(x+11)^2 + (y+ 6)^2 = 18^2 \\[/tex]
Equating it with:
[tex] (x-h)^2 + (y-k)^2 = r^2 \\
- h = 11\implies h = - 11\\
- k= 6\implies k = - 6\\
Center = (-h, \: - k) = (11,\: 6)\\
r^2 = 18^2 \\
Radius= 18\: units [/tex]
