circumference 4x^2+4y^2-8x+24y=24

circumference

4 x^{2} + 4 y^{2} - 8 x + 24 y = 24

C = 8 π

Solution steps

C = 2 π r

Find the radius

Radius given

4 x^{2} + 4 y^{2} - 8 x + 24 y = 24 : r = 4

C = 2 π 4

Refine

C = 8 π

x^{2} + y^{2} + 4 x - 10 y + 13 = 0

4 x^{2} + 16 x + 15 + 4 y^{2} + 6 y = 0

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

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

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