Astronomical measurements are often made by computing the small angle formed by the extremities of a distant object and using the arc length to approximate the chord. In the picture below, the full moon is shown to form an angle of 2° when the distance indicated is 248,000 miles. Estimate the diameter of the moon using this method (Round your answer to two decimal places).
