    Answer: 219.94\ cm^2

    Step-by-step explanation:

    Given

    The central angle of a sector measures 175^{\circ}

    The radius of the circle is r=12\ cm

    The area of the sector is given by

    \Rightarrow A=\dfrac{\theta }{360^{\circ}}\pi r^2

    Insert the values

    \Rightarrow A=\dfrac{175^{\circ}}{360^{\circ}}\cdot \pi \times 12^2\\\\\Rightarrow A=219.94\ cm^2
