circumference x^2-4x+y^2+8y-5=0

Solution

circumference

x^{2} - 4 x + y^{2} + 8 y - 5 = 0

Solution

C = 10 π

Solution steps

C = 2 π r

Find the radius

Radius given

x^{2} - 4 x + y^{2} + 8 y - 5 = 0 : r = 5

C = 2 π 5

Refine

C = 10 π

circumference 3x^2+3y^2=75 circumference

3 x^{2} + 3 y^{2} = 75

circumference 5x^2+5y^2-25=0 circumference

5 x^{2} + 5 y^{2} - 25 = 0

circumference x^2+y^2-4x-6y-3=0 circumference

x^{2} + y^{2} - 4 x - 6 y - 3 = 0

circumference x^2+(y-5)^2=25 circumference

x^{2} + (y - 5)^{2} = 25

circumference (x+4)^2+(y+3)^2=18 circumference

(x + 4)^{2} + (y + 3)^{2} = 18
