A person six feet tall walks around the earth. Assuming the earth is a perfect sphere, how many feet farther does the top of this person's head travel than the bottoms of his feet? Express your answer in terms of pi.

Hint: *The person's feet travel 2πR (R feet=Radius of Earth), and the person's head travels 2π(R+6) since that person is 6 feet tall.*

 

Hope you understand! :)
