<PRE><B>Question 113723</B>
A satellite makes a circular orbit around a planet of unknown diameter at an altitude of 1 mile above the planet. Then NASA boosted the satellite to an altitude of 2 miles above the planet. In the second orbit, the satellite travels how many miles farther than it travelled on the first orbit?(C=2 pie r) 
---------------
Circumference of 1st orbit:
C = 2(pi)(1/2mi) = pi miles
----------------------
Circumference of 2nd orbit:
C = 2(pi)*1mi = 2pi miles
-----------------------
It travels pi miles further in the 2nd orbit than in the 1st.
========================
