    You answer is 4.7

    Explanation

    I assume that the shaded region is the area inside of rectangle and outside the circle  

    so

    The shaded region is equal to the area of rectangle minus the area of circle

    step 1


    Find the area of rectangle


    The area of rectangle is equal to multiply the length by the width

    A= (3)-(11)=33 cm^2

    tep 2


    Find the area of the circle


    The area of the circle is


    A=\pi r^{2}


    we have


    r=3\ cm


    \pi =3.14


    substitute


    A=(3.14)(3^{2})


    A=28.26\ cm^{2}

    step 3


    Find the area of the shaded region


    33-28.26=4.74\ cm^{2}
