Three circles, each having radius equal to 4 cm, are drawn with the vertices of an equilateral triangle as the centres. If the length of each side of the triangle is equal to 8 cm, then what is the area (in $$cm^{2}$$) of the portion of the triangle that is NOT covered by the sectors of the circles?

A

16 $$\left(2\sqrt{3}-\pi\right)$$

B

8 $$\left(2\sqrt{3}-\pi\right)$$

C

8 $$\left(2\sqrt{3}-\frac{\pi}{2}\right)$$

D

16 $$\left(2\sqrt{3}-\frac{\pi}{2}\right)$$
