Absurd Math Error: Earth's Radius Only 4333 Feet?

A blogger discovered an unbelievable mathematical error in an image posted by a design and construction company. The image incorrectly calculated the Earth's radius when computing the lengths of two circular arcs at different altitudes, resulting in a radius of only 4333 feet, far less than the actual value. The blogger detailed the error in the calculation and pointed out the huge discrepancy between the actual Earth's radius and the calculated result. This erroneous calculation raises questions about the authenticity of information and highlights the importance of carefully verifying information in the information age.
