Hi we have an example in our book

The problem is to find the area of the sector and the area of the segment if the radius of the circle is 12 cm and the central angle is 60°.

And there's a thing we don't understand:

Area of 🔺AOC= ½ • (12)(6√3)

We do not understand where the 6√3 came from, it wasn't stated in the book can you please help?
