Correct Option: C
Area of sector
\(\frac{\theta}{360}\) x \(\pi\)r2, \(\theta\) = 60o, r = 3m
= \(\frac{60}{360}\) x \(\frac{12}{7}\) x 3 x 3
\(\frac{1}{6}\) x \(\frac{22}{7}\) x 9
= \(\frac{33}{7}\)
= 4.7m2
\(\frac{\theta}{360}\) x \(\pi\)r2, \(\theta\) = 60o, r = 3m
= \(\frac{60}{360}\) x \(\frac{12}{7}\) x 3 x 3
\(\frac{1}{6}\) x \(\frac{22}{7}\) x 9
= \(\frac{33}{7}\)
= 4.7m2
