circumference (x-1)^2+(y-3)^2=25

circumference

(x - 1)^{2} + (y - 3)^{2} = 25

C = 10 π

Solution steps

C = 2 π r

Find the radius

Radius given

(x - 1)^{2} + (y - 3)^{2} = 25 : r = 5

C = 2 π 5

Refine

C = 10 π

(x - 4)^{2} + (y + 2)^{2} = 16

x^{2} + y^{2} + 8 x + 4 y - 3 = 40

x^{2} + y^{2} \leq 9

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

x^{2} + y^{2} + 3 x + 2 y - 5 = 0

What is the circumference (x-1)^2+(y-3)^2=25 ?
The circumference (x-1)^2+(y-3)^2=25 is C=10pi
