Solve the equation for the indicated variable. Assume no denominator is 0.
-$A = 3 \pi a ^ { 2 }$, for $a$
A) $\mathrm { a } = \sqrt { 3 \pi \mathrm { A } }$
B) $\mathrm { a } = \frac { \pm \sqrt { 3 \pi \mathrm { A } } } { 3 \pi }$
C) $\mathrm { a } = \frac { \pm \sqrt { \mathrm { A } \pi } } { 3 }$
D) $\mathrm { a } = \frac { \pm \mathrm { A } \sqrt { 3 \pi } } { 3 \pi }$
