## Homework Statement

Assuming that the Earth describes in one year a circle, of 92500000 mile radius, whose center is the sun, how many miles does the Earth travel in a year?

## The Attempt at a Solution

How does knowing the radius of the Earth help me with this problem? I don't need the radius of the Earth I need to know the distance from the Earth to the sun which will be the radius... then I can solve it...

Is this correct?
