What is the formula that Eratosthenes discovered?
Eratosthenes of Cyrene was a Greek mathematician, elegiac poet, athlete, geographer, and astronomer. He was the first person to calculate the circumference of the earth by using a measuring system using stades, or the length of stadiums during that time period, and the tilt of the earth's axis.
Who was the mathematician first used the symbol pi?
The first mathematician to use the Greek letter π to represent the ratio of a circle's circumference to its diameter was William Jones, who used it in his work Synopsis Palmariorum Matheseos; or, a New Introduction to the Mathematics, of 1706.
What Greek invented pi?
Pi isn't an invention, it's a definition. It is defined as the ratio of any circle's circumference to it's diameter. If anything, it's a discovery. Euclidean geometry, attributed by Greek mathematician Euclid was the first recorded system used to show Pi as a mathematical constant. Archimedes was a famous ancient Greek mathematician and inventor. He accomplished the computation of pi.

The Greek geographer mathematician astronomer and poet who calculated the circumference of Earth was?
Eratosthenes
What is Eratosthenes?
He was an ancient Greek mathematician of the 2nd/3rd century BC, as well as a poet, geographer, musical composer, scholar, and astronomer. He was the first Greek to estimate the circumference and tilt of the earth. He created a map of the earth based on the knowledge available at the time. He was highly respected, and his calculations of the earth's circumference were used for hundreds of years. Today, his method for finding prime numbers from 1-100 is known as the 'Sieve of Eratosthenes' and is taught in math textbooks.
Who was the Greek mathematician who first calculated the circumference of the Earth?
The Greek mathematician who first calculated the circumference of the Earth was Eratosthenes. Around 240 BCE, he used measurements of the angles of shadows cast by obelisks in different locations in Egypt to estimate the Earth's circumference. His calculation was remarkably accurate for his time, demonstrating advanced understanding of geometry and geography.
Who created the formula of a circumference of a circle?
Archimedes, a famous Greek mathematician.
Who measured the size of the earth using a shadow stick and knowing the distance between two cities?
Eratosthenes, a Greek mathematician and astronomer, measured the size of the Earth using a shadow stick in the city of Alexandria and knowing the distance to the city of Syene. By observing the angle of the shadow at each location and using basic geometry, he was able to calculate the Earth's circumference.
Who was the first person to mesure the earth's circumference?
The first person credited with measuring the Earth's circumference was the ancient Greek mathematician and astronomer Eratosthenes. He used the angle of the shadow cast by a vertical stick in Syene and Alexandria to estimate the Earth's size with impressive accuracy for his time.
Who came up with circumference?
Archimedes, a famous Greek mathematician, born about 287 B.C.
Is it true or false that the Greek Eratosthenes is known for his calculation of the earths weight?
False. He is the first known person to calculate the circumference of the earth. Wikipedia has more information in their post on this interesting fellow. A link to the post is provided below.
What are facts on Eratosthenes?
Eratosthenes was a Greek mathematician and astronomer, named chief of the Library of Alexandria. He is recognized as the first person that calculated the circumference of Earth, he did it by his own rudimentary means and the results were quite accurate.
What scientist found Earth was round?
Greek mathematician and astronomer, Eratosthenes, is credited with determining that the Earth is spherical. In the 3rd century BCE, he calculated the Earth's circumference using the angle of the sun's rays at two different locations.
Who is aristarchus?
A Greek mathematician who believed (uncommonly) that the Earth was in orbit around the Sun.
Who invented the formula for finding The circumference of a Circle?
Archimedes, a famous Greek mathematician, born about 287 B.C.
