    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, \theta=\dfrac{\pi}{9}\ radian

    If \theta is in radian, the area of sector is given by :

    A=\dfrac{1}{2}r^2\theta\\\\A=\dfrac{1}{2}\times (3)^2\times \dfrac{\pi}{9}\\\\A=1.57

    So, the area of the sector is 1.57 unit square.
