circumference x^2+y^2+12x-12y+36=0

circumference

x^{2} + y^{2} + 12 x - 12 y + 36 = 0

C = 12 π

Solution steps

C = 2 π r

Find the radius

Radius given

x^{2} + y^{2} + 12 x - 12 y + 36 = 0 : r = 6

C = 2 π 6

Refine

C = 12 π

+ x^{2} + y^{2} + 8 x + 4 y - 3 = 40

x^{2} + y^{2} = 81

y^{2} = 4 - x^{2}

x^{2} + y^{2} + 4 x - 6 y + 12 = 0

(x - 2)^{2} + (y + 6)^{2} = 16

What is the circumference x^2+y^2+12x-12y+36=0 ?
The circumference x^2+y^2+12x-12y+36=0 is C=12pi
