Transform the Polar Equation to an Equation in Rectangular Coordinates $r=6 \cos \theta$

Transform the polar equation to an equation in rectangular coordinates. Then identify and graph the equation.
- $r=6 \cos \theta$

A)

$( x - 3 ) ^ { 2 } + y ^ { 2 } = 9 ;$ circle, radius 3 ,
center at $( 3,0 )$ in rectangular coordinates

B)


$x ^ { 2 } + ( y + 3 ) ^ { 2 } = 9 ;$ circle, radius 3,
center at $( 0 , - 3 )$ in rectangular coordinates

C)

$( x + 3 ) ^ { 2 } + y ^ { 2 } = 9$ ; circle, radius 3
center at $( - 3,0 )$ in rectangular coordinates

D)


$$x ^ { 2 } + ( y - 3 ) ^ { 2 } = 9 \text {; circle, radius } 3 \text {, }$$

center at $( 0,3 )$ in rectangular coordinates
