The planet Neptune orbits the Sun. Its orbital radius is 30.130.130, point, 1 astronomical units (\text{AU})(AU)left parenthesis, start text, A, U, end text, right parenthesis.
Assuming Neptune's orbit is circular, what is the distance it travels in a single orbit around the Sun?
Give your answer in terms of \piπpi.

The distance Neptune travels in a single orbit is .

Step-by-step explanation:

The distance that Neptune travels in a single orbit is the circumference of it's orbit.

The circumference of any circle of radius is

.

Therefore, the circumference of Neptune's orbit, which has a radius of 30.12 AU, is

Or, in Kilometers this is
