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.
When was earth diameter first estimated?
Eratosthenes of Cyrene (276 BC - 194 BC) was a Greek mathematician, poet, athlete, geographer and astronomer. He made several remarkable discoveries and inventions: he devised a system of latitude and longitude. He was the first person to calculate the circumference of the Earth with remarkable accuracy, and the tilt of the earth's axis.
How do scientists calculate earth?
Scientists use a variety of methods to calculate the size, shape, and composition of the Earth. This includes measurements taken from satellites, seismic studies, gravitational field measurements, and observations of the Earth's rotation and orbital motion. By combining data from these different sources, scientists can develop a comprehensive understanding of Earth's properties.
Who is the very first person on earth?
According to various religious texts, Adam and Eve are considered the first human beings created by God on Earth.
How old is the first person on earth?
the first person to live on earth was adem and eve
Contribution of eratosthenes?
Eratosthenes had many contributions : he was the first person to calculate the circumference of the earth he invented latitude and longitude he was the first person to prove earth was round he was the first to calculate the tilt of Earth's axis
What did eratosthenes create?
He invented the system of longitude and latitude.He was too the first person who calculate the circumference of the Earth.
Who invented area and circumference of a circle?
Actually, Eratosthenes of Cyrene (276? - 195? B.C.) was the first to calculate the Earth's circumference accurately. He is supposed to be the inventor.

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.
Who first estimated the circumference of the Earth?
erathosthenes was the first ,
Did Magellan discover the earth was round?
Although Ferdinand Magellan's expedition was the first circumnavigation of the Earth, many ancient scholars were already aware that the Earth was round. The Greek scientist Eratosthenes was the first to calculate the Earth's circumference, thus proving the Earth's roundness.
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.
IF the circumference of a circle is 6.28 what is the area?
The circumference and area of a circle, with radius r is: circumference = 2*pi*r and area = pi*r2 Use the first to calculate r and then the second to calculate the area.
When was the the circumference of the Earth first measured and by who?
One possible person is Eratosthenes of Cyrene ~230 BC as he was a Greek scientist who calculated the circumference of the Earth, with remarkable accuracy (some values for the "stadia" he used gives a result within 6% of the actual polar circumference). See link for further information
How do you calculate the circumference of a circle if you have the area is 8.2 com squared?
To calculate the circumference of a circle from its area, first use the formula for the area ( A = \pi r^2 ). Given that the area is 8.2 cm², you can solve for the radius ( r ) by rearranging the formula: ( r = \sqrt{\frac{A}{\pi}} ). Once you find the radius, use the circumference formula ( C = 2\pi r ) to calculate the circumference.
