A circle is centered at (−3, 2) and has a radius of 2. Which of the following is the equation for this circle?
(x + 3)2 + (y − 2)2 = 2
(x − 3)2 + (y + 2)2 = 4
(x + 3)2 + (y − 2)2 = 4
(x − 3)2 + (y + 2)2 = 2

Best ResponseYou've already chosen the best response.0Equation of a circle is \[\large (xh)^{2}~+~(yk)^{2}=r^{2}\] \[\large (h,k)~=~Center~coordinates~of~circle\] \[\large r~=~radius\] Plug in the h,k, and r, and tell me what you get :)

Best ResponseYou've already chosen the best response.0so would r= 2 and then h and k would be (3,2)? just wondering
