Question

What is the circumference of the Earth's orbit around the Sun?

Answer 1

Approximately `940` million kilometers.

Explanation:

A rough approximation can be deduced from the following data:

• The Earth's mean distance from the sun is approximately `150` million kilometers.

• The Earth's orbit is roughly circular.

The circumference of a circle is given by the formula `2pi r` where `r` is the radius.

So in the case of the Earth's orbit, it is roughly:

`2pi * 150 \ "million km" ~~ 940 \ "million km"`
