Answer:If the the Earth were smaller than it is and the Alexandria-to-Syene distance were the same, the shadow of the vertical pillar in Alexandria would be longer.
Explanation:Hope this answers your question
If the Earth were smaller and the distance between Alexandria and Syene was similar, the silhouette of the vertical pillar in Alexandria would be longer.
How was the distance between Alexandria and Syene?
Eratosthenes then measured the angle of a shadow produced by a stick at midday on the summer solstice at Alexandria and discovered it was around 7.2 degrees or 1/50 of a complete circle. He reasoned that if he knew how far Alexandria was from Syene, he could simply calculate the circumference of the Earth.
