To answer this question, we will use the following formula for the area of a sector:


A=(\alpha)/(360^(\circ))r^2\pi,

where r is the radius and α is the central angle.

Substituting α=120°, and r=8 in, we get:


A=(120^(\circ))/(360^(\circ))*64in^2\pi.

Simplifying the above result, we get:


A=(1)/(3)*64\pi in^2.

Answer: Option D.
