Question

What’s the correct answer for this?

Answer 1

Answer:

FIRST option is the correct answer

Step-by-step explanation:

First option is the correct answer.

$(x+11)^2 + (y+ 6)^2 = 324\\ (x+11)^2 + (y+ 6)^2 = 18^2$

Equating it with:

$(x-h)^2 + (y-k)^2 = r^2 \\- h = 11\implies h = - 11\\- k= 6\implies k = - 6\\Center = (-h, \: - k) = (11,\: 6)\\r^2 = 18^2 \\Radius= 18\: units$
