Estimating The Circumference Of The Earth Eratosthenes My Science Walks

If you measure the circumference of the Earth while passing through.

. He knew that the circumference of Earth constituted a circle of 360 degrees so 712 or 72 to divide 360 evenly by 50 degrees would. Mathematicians of his time had estimated Earths circumference to. He could then use simple proportions to find the Earths circumference72 degrees is 150 of 360 degrees so 800 times 50 equals 40000 kilometers. Aristotle not only taught that Earth was spherical but also mentioned early estimates of Earths circumference.

Celestial bodies are not. Eratosthenes divided 360 by 72 and got 50 which told him that the distance between Alexandria and Syene 500 miles was 150 of the total distance around the Earth. 40075017 km 24901461 miles 21638778 nautical miles The circumference of the Earth depends on the great circle that is measured. X 50 25000 mi.

Earth radius at sea level is 6378137 km 3963191 mi at the equator. Substitute this value to the formula for circumference. Or 5000 stadia for Eratosthenes was 150th multiplication gives you the earths circumference. This is the distance around the equator of the Earth.

And just like that an ancient. Using those measurements the equatorial circumference of. Planets - Calculate Circumference. So if 804 km or 500 mi.

It is 6356752 km 3949903 mi at the. Radius diameter and circumference Earths polar radius is 3950 miles 6356 km a difference of 13 miles 22 km. C Earth 2 π R Earth Length of the rope raised above the ground by any height h. 804 km x 50 40200 km.

For this calculation the longitude isnt needed. Mathematically Earth is a spheroid. The Equatorial Circumference of the Earth is. This decreases by the cosine.

Earths equatorial circumference is estimated to be around 24901 miles 40075 kilometers based on those measurements. You can also use it to find the area of a. Calculator for the equatorial circumferences of Sun Moon Earth and the planets in kilometers miles and compared to each other. The equatorial circumference of the Earth is 40075 km.

And for any of you. This gave him an angle of 712 degrees. C 2 π R 2 π 14 879646 cm. Length of the rope at ground level is equal to the Earths circumference.

The meridional circumference of Earth on the other hand is. At the equator the circumference of the Earth is 40070 kilometers and the day is 24 hours long so the speed is 1670 kilometershour 1037 mileshr.
