8 units

Step-by-step explanation:

Note that 120 degrees represents 1/3 of 360 degrees. The arc described here is thus 1/3 of the circumference of this circle.

Find this circumference and then multiply that result by 1/3:

The formula for the circumference of a circle with radius r is C = 2πr. Here,

(1/3) * (2) (π) (4 units) = 8.38 units, or (to the nearest integer) approx. 8 units.
