circumference x^2+y^2-4x-6y-12=0

circumference

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

C = 10 π

Solution steps

C = 2 π r

Find the radius

Radius given

x^{2} + y^{2} - 4 x - 6 y - 12 = 0 : r = 5

C = 2 π 5

Refine

C = 10 π

x^{2} + y^{2} = 5

3 x^{2} + 3 y^{2} + 4 y - 7 = 0

x^{2} + y^{2} + 4 x + 12 y - 100 = 0

x^{2} + y^{2} - 6 x + 4 y + 8 = 0

x^{2} + (y - 7)^{2} = 36

What is the circumference x^2+y^2-4x-6y-12=0 ?
The circumference x^2+y^2-4x-6y-12=0 is C=10pi
