Question

Help v qucik pleaseeeeee

Answer 1

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

passes through ( 4 , -4 )

$(4 - 4) {}^{2} + ( - 4 - 1) {}^{2} = r {}^{2}$

$r {}^{2} = ( - 5) {}^{2}$

$r {}^{2} = 25$

$r = \sqrt{25} = 5$

Your radius is 5 units

$c = 2\pi \: r \\ c = 2 \times 3.14 \times 5 \\ c = 31.4$

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

AND DRAW
