circumference x^2+y^2-12x+20y+72=0

circumference

x^{2} + y^{2} - 12 x + 20 y + 72 = 0

C = 16 π

Solution steps

C = 2 π r

Find the radius

Radius given

x^{2} + y^{2} - 12 x + 20 y + 72 = 0 : r = 8

C = 2 π 8

Refine

C = 16 π

x^{2} + y^{2} + 4 x + 12 y - 104 = 0

c i rc l e, f in d C i rc u m f ere n ce, g i v e n r = 3

(x - 5)^{2} + (y - 1)^{2} = 4

x^{2} + y^{2} \leq 1

x^{2} + y^{2} \leq 4
