If a girl 5 feet tall could walk around the equator, how many feet further would the top of her head travel than her feet? Assume that the earth is a sphere. Express your answer in terms of pi.

e = earth diameter in feet

 

(e+10) pi  -  e * pi = distance difference

epi + 10 pi  - epi

=     10 pi     feet
