First things first, let’s know who was Eratosthenes, then we will proceed for the answer to this task.

Eratosthenes of Cyrene was a Greek mathematician, geographer and astronomer (he yearned to understand the complexities of the entire world so he was devoted to many areas).[1] He lived between 276 BC – 194 BC and during that time he changed the way we view the world. He created geography and made some progress in science especially mathematics (he created a tool for discovering prime numbers).[2] He is now known for being the first person to measure the Earth’s circumference.
