Sagot :

[tex](x - 4) {}^{2} + (y - 1) {}^{2} = r {}^{2} [/tex]

passes through ( 4 , -4 )

[tex](4 - 4) {}^{2} + ( - 4 - 1) {}^{2} = r {}^{2} [/tex]

[tex]r {}^{2} = ( - 5) {}^{2} [/tex]

[tex]r {}^{2} = 25[/tex]

[tex]r = \sqrt{25} = 5[/tex]

Your radius is 5 units

[tex]c = 2\pi \: r \\ c = 2 \times 3.14 \times 5 \\ c = 31.4[/tex]

To Draw:

Place your center at the point x=4 and y=1

Then take your radius 5 units by going straight down left right or up by 5 units
