Circumference & Radius of Earth Term Paper

If you had done this significantly too early or too late, what kind of error would there have been your shadow length?

The shadow length would have a bigger value as sun's angle would have been smaller.

If you had done this significantly too early or too late, what kind of error would there have been your circumference value?

Such measurement would have given smaller sun angle value for the location, which would have been resulted in greater value of angle ?. In calculations greater value of ? wouls result in smaller value of estimated radius since its inversely proportional to angle ?.

4) Could astronauts on the Moon or Mars use this technique to determine the circumference of those objects?

Yes., such technique can be used to any astronomic….....
