Answer:
The distance the planet Neptune travels in a single orbit around the Sun is 60.2π AU.
Explanation:
As it is given that the Neptune's orbit is circular, the formula that we have to use is the circumference of a circle in order to find the distance it travels in a single orbit around the Sun. In other words, you can say that the circumference of the circle is equivalent to the distance it travels around the Sun in a single orbit.
The circumference of the circle = Distance Travelled (in a single orbit) = 2*π*R ---- (A)
Where,
R = Orbital radius (in this case) = 30.1 AU
Plug the value of R in the equation (A):
(A) => The circumference of the circle = 2*π*(30.1)
The circumference of the circle = 60.2π
Therefore, the distance the planet Neptune travels in a single orbit around the Sun is 60.2π AU.
