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.
What is a real world example of circumference?
The Equator is a real world example, being the circumference of the Earth.
How to calculate the circumference of the Earth?
To calculate the circumference of the Earth, you can use the formula C 2r, where C is the circumference, is a constant (approximately 3.14159), and r is the radius of the Earth. The average radius of the Earth is about 6,371 kilometers. Plug this value into the formula to find the circumference.
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?
Circumference of the earth at particular latitude can be determined using the formula, Circumference of the earth = 2*PI*r*cos(Φ0) where r = radius of the at particular latitude r = R * (1 - ((1 / 298.25722356) * (0.5 - 0.5 * COS (2 * Φ0)))) R= radius of the earth at equator Φ0= latitude
Who invented area and circumference of a circle?

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.
What measure could the circumference of the earth be determined?
The circumference of the Earth can be determined using the method of measuring the angle of the sun's shadow at two different locations at the same time. By knowing the distance between the two locations and the angle of the shadow, one can use basic trigonometry to calculate the Earth's circumference. This method was famously used by Eratosthenes in ancient Greece, who estimated the Earth's circumference with remarkable accuracy.
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 many times larger is the earth's circumference's than Luna?
The Earth is 3.64 times larger than Moon's Circumference. (Earth's Circumference) 39,843 divide by (Moon's Circumference) 10,921=3.64
