Question

Can you please teach me how to calculate the theoretical calculation part 

(a) Locate the legend on the globe beach ball. Measure in mm the length corresponding to 1000 km. Do your best to estimate to one decimal place. Write this value below. and use this conversion factor for subsequent problems. No additional explanation is required. The Value would be 29mm. I For the following questions, assume that the Earth is a sphere of radius re = 6378.1 km. Calculate the distance along the surface between the points following the shortest possible path that adheres to the specified requirements. For distance, only the absolute value matters, and none of your answers should have a negative sign. First measure the distance on the globe beach ball, then calculate it theoretically assuming that the Earth is a perfect sphere. Then calculate the percent difference and discuss possible reasons for differences. Note that the solid latitude and longitude lines on the globe are printed in increments of 10°. (b) Consider two points on the equator at coordinates (latitude, longitude) of (0°N, 20°E) and (0°N, 20⁰W). Measured distance on the globe (in mm to one decimal place, no need to show work): 97mm Measured distance converted (to nearest km): 1 Theoretical calculation (to nearest km):
