~ Circumference:
24,901.55 miles (40,075.16 kilometers) - at the equator
24,859.82 miles (40,008 kilometers) - through the poles
~ Diameter:
7,926.41 miles (12,756.32 kilometers) - at the equator
7,901 miles (12,715.43 kilometers) - through the poles
Earths diameters is a straight line through the middle of the Earth. That is how the size of planets is measured.
Our planet is measured in miles (diameter)
The diameter of the Earth, when measured as a globe, is approximately 12,742 kilometers (7,918 miles). However, because the Earth is not a perfect sphere but an oblate spheroid, its equatorial diameter is slightly larger than its polar diameter, which is about 12,714 kilometers (7,900 miles).
Yes, Eratosthenes estimated the Earth's diameter using the angle of the sun's rays at two different locations on the same day. By measuring the difference in the angles, he was able to calculate the Earth's circumference and thus its diameter.
7926 miles and 12760 km. Thats Pretty long.
The diameter is measured using a tape measure.
Diameter.
In the US its diameter is measured in inches.
A diameter is measured by using a ruler. However, you also could use a digital caliper to measure the diameter of a circle.
because the chord can be determine by the diameter and the diameter can be determine by the chord.
Tube is measured by outside diameter, pipe is measured by inside diameter.
A diameter is a linear measurement that needs units. However, assuming that the units are kilometers, the Earth is about 12,700 kilometers in diameter. Venus is a little smaller at 12,100 kilometres.
