What is the center and radius of the circle given by the following equation?
$x^2 + y^2 - 18x + 6y + 65 = 0$
1. $"Center": (18, -6), \ "Radius": 65$
2. $"Center": (9,-3), \ "Radius": 5$
3. $"Center": (0,0), \ "Radius": sqrt(65)$
4. $"Center": (-9,3), \ "Radius": 25$
$(x-1)^2+(y+2)^2=12$
1. Center (-1,2); Radius of $2sqrt3$
2. Center (1,-2); Radius of $2sqrt3$
3. Center (1,-2); Radius of 12
4. Center (-1,2); Radius of 12
