Answer:
The area of the sector is 1.57 unit square.
Step-by-step explanation:
Given that,
Radius of circle, r = 3
Angle of sector, [tex]\theta=\dfrac{\pi}{9}\ radian[/tex]
If [tex]\theta[/tex] is in radian, the area of sector is given by :
[tex]A=\dfrac{1}{2}r^2\theta\\\\A=\dfrac{1}{2}\times (3)^2\times \dfrac{\pi}{9}\\\\A=1.57[/tex]
So, the area of the sector is 1.57 unit square.
