# Question #e696b

a) $3.6 \cdot {10}^{- 3} {m}^{2}$
a) is the only possibly correct answer since the other two have units which are not areas (both $m$ and $m m$ are linear measures).
$\textcolor{w h i t e}{\text{XXX}} A = 4 \pi {r}^{3}$
The only possible trick here is in converting between $c {m}^{3}$ and ${m}^{3}$ (or maybe handling scientific notation).
