A circle is centered at (7, 8) and has a radius of 11. Which of the following is the equation for this circle?
(x − 7)^2 + (y − 8)^2 = 121
(x − 7)^2 + (y − 8)^2 = 11
(x + 7)^2 + (y + 8)^2 = 121
(x + 7)^2 + (y + 8)^2 = 11

Best ResponseYou've already chosen the best response.1make a guess, i bet you are right general form is \[(xh)^2+(yk)^2=r^2\] put \(h=7,k=8,r=11\)

Best ResponseYou've already chosen the best response.0so (x7)^2+(y8)^2=11^2 ?

Best ResponseYou've already chosen the best response.1yeah although they need you to square 11

Best ResponseYou've already chosen the best response.0all @misty1212 was saying is that in your answer choices the 11 is squared

Best ResponseYou've already chosen the best response.1\[(x7)^2=(x7)(x7)=x(x7)7(x7)=x^27x7x+49 \\ =x^214x+49\] no your choices do not have this form

Best ResponseYou've already chosen the best response.1\[(xh)^2+(yk)^2=r^2 \\ \text{ you are give} (h,k)=(7,8) \text{ and } r=11 \\ \text{ just plug into this form }\] I think @satellite73 already walked you though this
