Find the area of the shaded portion in the equilateral triangle with sides 6. (assuming the central point of each arc is its corresponding vertex) BTW; Answer should be in this form: A= X*square rootX - X/X*pi
Equilateral Triangle. So angles are all 60°. So you can find the area of the 3 sectors. You can also find the area of the whole triangle - first you need to find the height using Pythagorean theorem. Then find area of triangle and subtract the area of 3 sectors from that.
I don't understand the last part about the form in which you need to express it.
I got\[\frac{ 30 - 9\pi }{ 2 }\]
