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

Solution

circumference

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

Solution

C = 4 π

Solution steps

C = 2 π r

Find the radius

Radius given

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

C = 2 π 2

Refine

C = 4 π

Popular Examples

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

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

circumference x^2+y^2=36 circumference

x^{2} + y^{2} = 36

circumference x^2+y^2=16 circumference

x^{2} + y^{2} = 16

circumference 4x^2+4y^2=64 circumference

4 x^{2} + 4 y^{2} = 64

circumference x^2+y^2+4y-60=0 circumference

x^{2} + y^{2} + 4 y - 60 = 0
