![If \( A \) is the area of the circle, then \( A_s = \frac{A \theta}{2 \pi} \) represents the area of the sector, because \( \frac{\theta}{2 \pi} \) gives the fraction of the area covered by the sector.
Find the area of the sector formed by central angle \( \theta \) in a circle of radius \( r \) if
\[ \theta = \frac{\pi}{3} \, ; \, r = 2 \, \text{m} \]
\[ \boxed{ \phantom{} } \] \( \text{m}^2 \)
