Need help!
Will fan and medal!!
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.0well the general form of a circle is \[(x  h)^2 + (y  k)^2 = r^2\] the centre is (h, k) and r is the radius so substitute your information and get a solution.

Best ResponseYou've already chosen the best response.0well you are told the centre is (3, 2) and radius is 2 so h = 3 k = 2 and r = 2

Best ResponseYou've already chosen the best response.0the answer isn't B.. just substitute correctly h =  3 so (x  h) = ( x (3) which becomes (x + 3)
