circumference x^2+y^2-6x+10y+9=0

circumference

x^{2} + y^{2} - 6 x + 10 y + 9 = 0

C = 10 π

Solution steps

C = 2 π r

Find the radius

Radius given

x^{2} + y^{2} - 6 x + 10 y + 9 = 0 : r = 5

C = 2 π 5

Refine

C = 10 π

x^{2} + y^{2} - 2 x + 6 y = 6

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

x^{2} + (y - 3)^{2} = 4

(x - 4)^{2} + (y + 1)^{2} = 41

2 x^{2} + 2 y^{2} - 24 x + 28 y + 120 = 0

What is the circumference x^2+y^2-6x+10y+9=0 ?
