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

Solution

circumference

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

Solution

C = 4 π

Solution steps

C = 2 π r

Find the radius

Radius given

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

C = 2 π 2

Refine

C = 4 π

Popular Examples

circumference x^2+y^2+4x-2y+1=0 circumference

x^{2} + y^{2} + 4 x - 2 y + 1 = 0

circumference (x-1)^2+y^2=4 circumference

(x - 1)^{2} + y^{2} = 4

circumference (x+2)^2+(y-1)^2=25 circumference

(x + 2)^{2} + (y - 1)^{2} = 25

circumference x^2+(y-3)^2=20 circumference

x^{2} + (y - 3)^{2} = 20

circumference x^2-3x+4y+y^2=16 circumference

x^{2} - 3 x + 4 y + y^{2} = 16
