Answer 2

Eratosthenes was the first to determine the perimeter of the Earth.

Eratosthenes was a Greek mathematician, astronomer and geographer. He calculated the circumference of the Earth by making a comparison of the angles of the sun at two points. He also calculated the tilt of the axis of the Earth accurately.

Eratosthenes is also believed to have invented the leap day and calculated the distance between the sun and earth with precision.
