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!
WebJan 29, 2024 · Therefore, to find the speed of Earth's rotation around its middle, divide 40,000 km by 24 hours to get 1,670 km per hour. As one moves north or south in latitude from the equator the Earth's circumference is reduced and thus the speed of rotation decreases slightly. WebJan 31, 2024 · The horizon at sea level is approximately 4.5 km. To calculate it, follow these steps: Assume the height of your eyes to be h = 1.6 m. Build a right triangle with hypotenuse r + h (where r is Earth's radius) …
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. WebIf the earth is a globe, and is 25,000 English statute miles in circumference, the surface of all standing water must have a certain degree of convexity—every part must be an arc of a circle. ...
