circumference x^2+y^2+5x+20y+10=0

circumference

x^{2} + y^{2} + 5 x + 20 y + 10 = 0

C = 385 π

Solution steps

C = 2 π r

Find the radius

Radius given

x^{2} + y^{2} + 5 x + 20 y + 10 = 0 : r = \frac{385}{2}

C = 2 π \frac{385}{2}

Refine

C = 385 π

x^{2} + y^{2} + 2 x + 6 y - 104 = 0

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

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

x^{2} + y^{2} - 6 x - 4 y + 9 = 0
