One of the equations below is the equation of a circle of radius 6.
Identify this equation.
Tick one box.
(x−4)2+(y+1)2=6(x - 4)^2 + (y + 1)^2 = 6(x−4)2+(y+1)2=6
(x−4)2+(y+1)2=36(x - 4)^2 + (y + 1)^2 = 36(x−4)2+(y+1)2=36
(x−4)2−(y+1)2=36(x - 4)^2 - (y + 1)^2 = 36(x−4)2−(y+1)2=36
(x−4)2+(y+1)2=−36(x - 4)^2 + (y + 1)^2 = -36(x−4)2+(y+1)2=−36
