circumference 5x^2+5y^2-30y-5=0

circumference

5 x^{2} + 5 y^{2} - 30 y - 5 = 0

C = 210 π

Solution steps

C = 2 π r

Find the radius

Radius given

5 x^{2} + 5 y^{2} - 30 y - 5 = 0 : r = 10

C = 210 π

x^{2} + y^{2} + 5 y = 12

(x - 2)^{2} + (y - 3)^{2} = 36

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

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

x^{2} + y^{2} - 6 x + 6 y - 3 = 0
