Answer: 353.77

Explanation:

Let's start by considering the sector ACB.

The area of this sector is
\pi \cdot 24^(2) \cdot (120)/(360)=192\pi

Now, let's consider the area of triangle ACB. Its area is given by:


(1)/(2) \cdot 24 \cdot 24 \cdot \sin 120^(\circ)=144√(3)

So the area of the shaded segment is
192\pi -144√(3) \approx 353.77
