The area of a sector of a circle of radius 6 cm with central angle 120° is:

Question

Accepted Answer

1. Use the sector area formula: $A=\dfrac{	heta}{360}\pi r^2$.

2. Put $	heta=120^\circ$ and $r=6$: $A=\dfrac{120}{360}\pi	imes6^2$.

3. Simplify: $\dfrac{120}{360}=\dfrac{1}{3}$ and $6^2=36$, so $A=\dfrac{1}{3}	imes36\pi=12\pi$.

4. So the correct choice is **(a) 12π cm²**.
