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

Solution

circumference

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

Solution

C = 8 π

Solution steps

C = 2 π r

Find the radius

Radius given

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

C = 2 π 4

Refine

C = 8 π

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

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

circumference (x-3)^2+(y+2)^2=25 circumference

(x - 3)^{2} + (y + 2)^{2} = 25

circumference x^2+y^2=100 circumference

x^{2} + y^{2} = 100
