circumference x^2+y^2=20

Solution

circumference

x^{2} + y^{2} = 20

Solution

C = 45 π

Solution steps

C = 2 π r

Find the radius

Radius given

x^{2} + y^{2} = 20 : r = 20

C = 2 π 20

Refine

C = 45 π

Popular Examples

circumference (x-5)^2+(y+2)^2=16 circumference

(x - 5)^{2} + (y + 2)^{2} = 16

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

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

circumference x^2+y^2=12 circumference

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

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

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

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

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