How did people measure how big the world is by using the pyramids?

Answer 1

it was 2 sticks not the pyramids that man first measured the circumference his name was Eratosthenes a greek geometer by measuring the shadow of astick in Alexandria and one in Aswan just google this man and you will find his story as far as using the pyramids to measure the circ of earth i dont ever recall hearing of that theory ever

Answer 2

Nobody did. They planned on picking up the pyramids and setting them down repeatedly, but they proved to fragile.
The circumference (and therefore diameter) was determined in Egypt by noting what day the sun at noon shined down a deep well (the sun appearing in a reflection at the bottom) at a site on the equator and measuring the angle of the sun on the same day (actually several days in a row) from a plumbline, knowing the distance between the points and using the data to compute the distance around the world.

Answer 3

That's a new one for me. The most famous measurement was made by a Greek who measured the angle of the sun down a well at Alexandria in Egypt and a point further south on the Nile River. By the difference in angle and distance from the two places, he estimated the circumference to about a 2% error.

Answer 4

they dont
