Greek scholar and philosopher Eratosthenes (276 BC - 195 BC) figured out that the length of the shadow at exactly noon, drawn from a stick of a certain length, stuck in the ground in Aswan, Egypt, was of a different length than the shadow at exactly noon, drawn from a similar stick in Alexandria, Egypt. From this, the circumference of the Earth was calculated, and the diameter and radius soon followed.

Which of the rare earth metals is the smallest?
The smallest calculated atomic radius is for lutetium - 217 pm.
What is the formula for figuring curvature of the earth in any given direction?
The curvature of the Earth in any direction can be calculated using the formula for the Earth's radius of curvature (R), which is given by R = a / √(1 - e^2sin²φ) where a is the equatorial radius of the Earth and e is the eccentricity of the Earth. By determining the radius of curvature at a specific latitude (φ), you can find the curvature in that direction.
What is Venus' radius as compared to the Earth's?
Venus has a radius of about 6,052 kilometers, which is about 95% of Earth's radius.
How do you get a radius of a circumference?
The circumference of a circle is calculated by multiplying the radius by 2xPI PI is approximately 3.141 This means the radius can be calculated by dividing the circumference by 2xPI
What is the relation between mass of earth and its radius?
For any object, the mass is the product of its volume and its density. In the case of Earth, that would be the averagedensity. The volume, of course, can be calculated on the basis of its radius. Use the formula for a sphere; that's close enough for most purposes.
How does Venus compare with the earth radius and mass?
Venus' radius = 0.95 of Earth's Venus' mass = 0.815 of Earth's

The Earth's radius is approximately 6,371 kilometers and 3,959 miles.
Who invent radius of earth?
If you are a believer, then God did but if you are not, then nobody did. The radius of the earth existed and therefore ots radius did before there was any form of life on earth to invent it.
What is the radius of earth in kilometers?
