Satellite A has an orbital radius 3.00 times greater than that of satellite B. Satellite B's orbital period around Earth is 120 minutes. What is satellite A's orbital period?

Respuesta :

To find the circumference (orbit) of an object, you use Pi x Diameter. 
As you have the circumference of B, you divide it by Pi to get the Diameter. 
So 120 divided by 3.141592654 = 38.2 minutes for the Diameter. 

As' radius and Diameter will be 3x greater than B. 
38.2 x 3 = 114.6 
To get back to the orbital period, times 114.6 by Pi, and you will get 360 minutes. 

I don't know the answer, but it IS NOT "360 minutes" for Plato users. I got it wrong.
