POTM+5

Problem of the month (POTM) #5

Please go to this page if you are a guest and would like to provide feedback and/or some ideas of how to solve this problem.

The Earth’s Circumference A steel band is placed around the earth, snugly fit at the equator. (The equator is approximately 25,000 miles in circumference.) This band is cut, and a 36 inch piece of string is added to the steel band. This new circular band is placed around the earth, hovering above the earth’s surface, with its center being the center of the earth. A gap is created between the equator and this circular band.

How wide is this gap?
