Question 1153285
.
<pre>

The difference is {{{2pi}}} times the person's height,


so the <U>ANSWER</U> is  {{{2*3.14*1.7}}} = 10.68 meters.


Indeed, the difference = {{{2*pi(R+h)}}} - {{{2*pi*R}}} = {{{2*pi*h}}}.

An amazing fact is that 

<pre>
    this difference does not depend on the value of the radius of the Earth (!)
