Circumference of globe in km
WebIf we construct a right triangle where one angle is 60 degrees (half of 120 degrees), "d" is the distance to the earth, and "r" is the radius of the earth, then d = r/tan (60) = 6371 km/1.732 = 3678 km = 2285 miles. This says that you would have to be 3678 km (2285 miles) away from the earth to see it as a full disk. Webcircumference of the Earth: c = 250,000 x .1 = 25,000 miles. Modern estimates of the Earth’s circumference place it at 24,860 miles. (This is the circumference of a great circle that passes through the north and south poles. The circumference of the equator is 24,900 miles.) Hence, Eratosthenes’ estimate is off by

WebWe can use this to estimate the circumference if we know the diameter, and vice versa. For example, using 3.1 as an approximation for \pi, if a circle has a diameter of 4 cm, then the circumference is about (3.1)\boldcdot 4 = 12.4 or 12.4 cm. The relationship between the circumference and the diameter can be written as \displaystyle C = \pi d WebSep 7, 2024 · Today we know our planet's circumference is roughly 40,000 kilometers (24,850 miles). Not bad for a more than 2,000-year-old estimate made with no modern technology!

WebAnother formula to find the circumference is if you have the diameter you divide the diameter by 2 and you get the radius. Once you have the radius you times the radius by 2 and times it by pie and then you get the circumference. Here are the two different formulas for finding the circumference: C = πd. C = 2πr.
