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 the circunference of hemisphere?
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.
pi times diameter = circumference
The answer will depend on what is meant by "how do you you do" or even "how do you do". I do not do circumference. A can draw it, I can calculate it, I can calculate other measures (area, radius, diameter) from it but I do not DO it!
Eratosthenes
Around 240 BC.
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.
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.
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
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.
He invented the system of longitude and latitude.He was too the first person who calculate the circumference of the Earth.

The Earth's circumference is about 10 times larger than the Moon's circumference.
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.
