The chicken will fit underneath.For each circle, the radius and the circumference are related bycirc = 2 * pi * radiusfor the earth itself: 25,000 mi = 2 * pi * radius_of_earthfor the wire:25,000 mi + 3 feet = 2 * pi * radius_of_wirerearrange and combine:radius_of_wire = (25000 mi + 3 feet) / (2 * pi) = 25000 mi / (2*pi) + 3 feet / (2*pi) = radius_of_earth + 3 feet / (2*pi) the height of the wire is the difference between the two radii,which is 3 feet / (2*pi), which works out to something like 5-6 inch.
