Problem

An equilateral triangle has side length 8. The area of the region containing all points outside the triangle but not more than 3 units from a point on the triangle is : (1) 9(8+π)9(8 + \pi) (2) 8(9+π)8(9 + \pi) (3) 9(8+π2)9\left(8 + \frac{\pi}{2}\right) (4) 8(9+π2)8\left(9 + \frac{\pi}{2}\right)
