Answer: 189.028 AU.
Step-by-step explanation:
Given: The radius of the orbit = 30.1 AU
Since, the orbit is circular in shape, then the distance traveled by Neptune is given by:-
[tex]\text{Circumference=}2\pi r\\\\\Rightarrow\ \text{Circumference=}2(3.14)\times(30.1)\\\\\Rightarrow\ \text{Circumference=}=189.028\text{ AU}[/tex]
Hence, the distance traveled by Neptune in a single orbit around the Sun = 189.028 AU.
