Answer: [tex]12\pi[/tex] square units

Step-by-step explanation:

Area of sector is given by :

[tex]A=\dfrac{x}{360^{\circ}}\pi r^2[/tex] , where x is the central angle made by arc and r is the radius of the circle .

As per given , we have

[tex]x=120^{\circ}[/tex]

Radius = 6 units

Then, the  area of the sector made by arc will be :

[tex]A=\dfrac{120^{\circ}}{360^{\circ}}\pi (6)^2\\\\=\dfrac{1}{3}\pi (36)=12\pi[/tex]

Hence, the area of the sector of the circle formed by this central angle = [tex]12\pi[/tex] square units.
