In 250 BC who determined the size of the earth?
Eratosthenes
How did eratosthenes determine the size of the earth?
Eratosthenes determined the size of the Earth by measuring the angle of the shadow cast by a vertical stick in two different locations on the same day. By comparing the angles at the two locations and knowing the distance between them, he was able to calculate the Earth's circumference.
Describe how eratosthenes measure the size of Earth?
Eratosthenes measured the size of Earth by using the Sun's angles, as well as a bit of geometry.
Who made the first attempt to determine the size of the earth?
Eratosthenes
The first accurate measurement of the size of Earth was made by .?
Eratosthenes
Ertaosthenes determined the circumference of earth by conducting an experiment what are the steps?
Eratosthenes calculated the Earth's circumference by measuring shadows at two different locations at the same time. He then used the angles of the shadows cast by a vertical stick to calculate the Earth's circumference using geometry and trigonometry. By comparing the shadow angles at two different locations, Eratosthenes was able to estimate the Earth's size accurately.
Eratosthenes determined the circumference of the earth by conducting an experince put his step in order as they correlate to the scientific to the method?
Certainly! Eratosthenes estimated the Earth's circumference by comparing the angles of the sun's shadow at two different locations and using the distance between them. By measuring the shadows cast by objects, he calculated the angle of the sun's rays at each location, leading to an accurate estimate of the Earth's size, which was remarkably close to the current value.
What describes how Eratosthenes discovered the approximate circumference of the earth?
Which of the following describes how Eratosthenes discovered the approximate circumference of the earth
Who were the first people to calculate the size of the Earth and the Earth-Moon distance?
The first people to calculate the size of the Earth and the Earth-Moon distance were the ancient Greek mathematician and astronomer, Eratosthenes, and the ancient Greek astronomer and mathematician, Hipparchus.
Who found circumference of earth?
Eratosthenes
Who is calculate the circumference of earth?
Eratosthenes
What year did Eratosthenes die?
Eratosthenes is famous for making the first good measurement of the size of the Earth. He lived from 276 to 194 B.C. and died in Alexandria at age 82. He was rumored to have starved himself to death after going blind.
