Complete the Square and Write the Equation in Standard Form $$12 x ^ { 2 } + 12 y ^ { 2 } = 144$$

Multiple Choice

Complete the square and write the equation in standard form. Then give the center and radius of the circle.
- $$12 x ^ { 2 } + 12 y ^ { 2 } = 144$$

A) $x ^ { 2 } + y ^ { 2 } = 12$
$( 0,0 ) , r = 2 \sqrt { 3 }$
B) $x ^ { 2 } + y ^ { 2 } = 12$
$( 0,0 ) , r = 12$
C) $x ^ { 2 } + y ^ { 2 } = 144$
$( 0,0 ) , r = 12$
D) $( \mathrm { x } - 12 ) ^ { 2 } + ( \mathrm { y } - 12 ) ^ { 2 } = 12$
$( 12,12 ) , \mathrm { r } = 2 \sqrt { 3 }$
