circumference (x+7)^2+(y-1)^2=8

circumference

(x + 7)^{2} + (y - 1)^{2} = 8

C = 42 π

Solution steps

C = 2 π r

Find the radius

Radius given

(x + 7)^{2} + (y - 1)^{2} = 8 : r = 8

C = 2 π 8

Refine

C = 42 π

c i rc l e, f in d C i rc u m f ere n ce, g i v e n r = 7

x^{2} + y^{2} - 6 x + 2 y - 1 = 0

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

(x - 4)^{2} + (y + 4)^{2} = 36

(x - 7)^{2} + (y - 3)^{2} = 9

What is the circumference (x+7)^2+(y-1)^2=8 ?
The circumference (x+7)^2+(y-1)^2=8 is C=4sqrt(2)pi
