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.
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
The earth has a diameter of 12756.32 km. What is the circumference of the earth?
Multiply the diameter by pi to find the circumference
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.
How do you calculate the area of a circle when you have the circumference?
you divide the circumference by pi to get diameter then divide that by 2 to get radius then square the radius and multiply it by pi
When did euratosthenes calculate the circumference of the earth?
It is not known when, or even if, Euratosthenes did calculate the circumference of the earth. However, it is known that a very accurate estimate was obtained by Eratosthenes in the early years of the third century BC.
What year did eratosthenese calculate the circumference of the earth?
Around 240 BC.
How do you determine the circumference of the earth if you know a circumference of a smaller latitude and the number of degrees the latitude is from the equator?
You can use the relationship between the circumference of the Earth and the circumference of the smaller latitude to calculate the Earth's circumference. Multiply the circumference of the smaller latitude by the cosine of the latitude. This will give you the circumference of a circle at that latitude, which can then be used to estimate the Earth's circumference.
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.
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
How can altitude be used from 2 different locations to calculate the circumference of the earth?
Altitude measurements taken from two different locations can be used to calculate the circumference of the Earth using trigonometry. By measuring the angle of elevation to the same point in the sky from the two locations and knowing the distance between them, it's possible to calculate the circumference. This method is based on the principles of triangulation and spherical geometry.
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.
How do you calculate circumference?
to calculate circumference you find a circles radius or diameter. you do diameter times pi or radius times 2 times pi. the you have circumference!
How do you calculate circumference of hemisphere?
how do you calculate the circunference of hemisphere?
How can you put the word circumference in a sentence?
His prime objective was to measure a degree on the equator to calculate the circumference of the earth.Studies have shown there has been a large increase in waist circumference in young people.The earth's circumference was accurately measured around 240 BCE by Eeratosthenes.It isn't easy to measure the circumference of large items.
How many times larger is the earth's circumference's than Luna?
The Earth's circumference is about 10 times larger than the Moon's circumference.
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.
