Answer: B. [tex](x-11)^2+(y+2)^2=81[/tex]
Step-by-step explanation:
The standard form of a circle is described by the following equation:
[tex](x-a)^2+(y-b)^2=r^2[/tex]
Your center is [tex](11,-2)[/tex] and your radius is [tex]r=9[/tex]
Plug them into the equation and this is what you get:
[tex](x-11)^2+(y-(-2))^2=9^2[/tex]
Simplify and you get:
[tex](x-11)^2+(y+2)^2=81[/tex]
Your answer should be b.
