    you can do the area of that entire 120 degree region and then take away the area of that 120 degree triangle probably

    The area of a circle is pi*radius^2, the area of the pie slice angle 120 is \[\pi*24^2*\frac{ 120 }{ 360 } = 192\pi \approx 603.19\] The triangle TCS has area \[144\sqrt{3} \approx 249.42\]

    subtracting the two, the shaded area is 603.19-249.24 = 353.77

    \[Area: A=\left(\begin{matrix}1 \\ 2\end{matrix}\right)r ^{2}(\alpha-\sin \alpha)\left[ 1 \right]\]

    i think the formula is S= THETA/180 *PI*RADIUS

    arc length = radius * angle \[s=r*\theta \]
