Question 595412
A steel band circles the earth at the equator.
 It is assumed that the steel does not stretch or shrink and that the earth is a perfect sphere.
 If the band were lengthened so that it is 6" above the equator at all points around the earth, what length must be added to the band?
:
That would add 12" to the diameter, hence {{{pi*12}}} = 37.7" added to the circumference
