Question

The planet neptune orbits the sun. its orbital radius is 30.1 astronomical units (AU). assuming neptunes orbit is circular, what is the distance it travels in a single orbit around the sun?

Solve in terms of pi.

Answer 1

The distance it travels in a single orbit around the sun is
`60.2\pi`

Explanation:

Given : The planet Neptune orbits the sun. its orbital radius is 30.1 astronomical units (AU). Assuming Neptune orbit is circular.

To find : What is the distance it travels in a single orbit around the sun?

Solution :

The radius of the orbital is 30.1 AU.

We have given that assume orbit is circular.

So, distance travels in a single orbit is circumference of the orbit.

Circumference is
`C=2\pi r`

r=30.1 AU

`C=2\pi * 30.1`

`C=60.2\pi`

Therefore, The distance it travels in a single orbit around the sun is
`60.2\pi`
