Answer 1

Answer: The correct statement is ' the Size of the Earth'.

Step-by-step explanation:

Most Greek scholars soo many years agreed that the earth was shperical in shape but never knew the size of the Earth.

Eratosthenes was a man of many talents, he was a geographer, a mathematician, an astronomer and a historian. With the expanse of knowledge he had, he compared the position of the sun and the shadows cast at noon on the summer solstice in two different cities. With reasonable accuracy, he was able to determine the shperical size of the earth. He computed this by using simple geometry and trigonometry and by recognizing Earth as a sphere in space.
