Find the area of the shaded portion in the equilateral triangle with sides 6. show all work for full credit. (hint: assume that the central point of each arc is its corresponding vertex.)

So... if you notice the picture below

each circle, has their central angle at the vertex of the triangle
that simply means, 3 circles with a radius of 3, overlapping the triangle

now, the area in the middle, the shaded one, will be, the whole area of the triangle MINUS those 3 circle sectors

hmmmm each sector has 60°, that means, all three of them will then be 60+60+60 or 180°, so the area of those three sectors, can be combined into a 180° sector, well, hell, 180° is really half a circle

so.... the area of those three sectors of 60° each, all three combined, is the same area of half a circle with a radius of 3

so    



you can, add the fractions if you want, or leave them like that, or get their difference by using their decimal format
