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

circumference

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

C = 10 π

Solution steps

C = 2 π r

Find the radius

Radius given

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

C = 2 π 5

Refine

C = 10 π

(x - 1)^{2} + (y - 2)^{2} = 3^{2}

(x - 5)^{2} + (y - 9)^{2} = 4

(x - 3)^{2} + (y - 3)^{2} = 7

(x - 5)^{2} + y^{2} = 4

x^{2} + y^{2} - 8 x + 6 y + 16 = 0

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