Best ResponseYou've already chosen the best response.1equation of a circle is \[(xh)^2 + (yk)^2 = r^2\] where (h,k) is the center and r is the raidus does that help

Best ResponseYou've already chosen the best response.0(x + 2)2 + (y – 1)2 = 64 (x – 2)2 + (y + 1)2 = 64 (x – 2)2 + (y + 1)2 = 8 (x + 2)2 + (y – 1)2 = 8

Best ResponseYou've already chosen the best response.1the center of a circle is (3, 4) and radius is 5 he equation would be \[(x 3)^2 + (y  4)^2 = 5^2\] \[\implies (x3)^2 + (y+4)^2 = 25\] got the idea now?
