What is the radius of the core?
Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).

How was the diameter of Earth measured first?
The Greek philosopher Aristotle (384-322 B.C.) is credited as the first person to try and calculate the size of the Earth by determining its circumference (the length around the equator) He estimated this distance to be 400,000 stades (a stadia is a Greek measurement equaling about 600 feet).
What is called diameter?
Diameter of a circle The diameter is the length of the line through the center that touches two points on the edge of the circle.

What is the radius of the earths crust?
The thickness of the Earth's crust is actually quite variable ranging from 5-10 km in oceanic regions to 20-70 km for continental crust….
| Actual Value | Scale Value (1:10 million Scale) | |

What is the radius of the earth * 1?
6,378.1370 km The Earth's equatorial radius a, or semi-major axis, is the distance from its center to the equator and equals 6,378.1370 km (3,963.1906 mi).
What is the real radius of Earth?
The Earth's mean radius is determined as the average distance from the physical center to the surface, based on a large number of samples. The value, symbolized rearth, is equal to approximately 6,371,000 meters (6.371 x 106 m). This is roughly 6,371 kilometers (km) or 3,960 statute miles.

Who discovered Earth?
The first person to determine the size of Earth was Eratosthenes of Cyrene, who produced a surprisingly good measurement using a simple scheme that combined geometrical calculations with physical observations.
Who discovered Earth round?
In the 3rd century BC, Hellenistic astronomy established the roughly spherical shape of Earth as a physical fact and calculated the Earth's circumference.
How do you find the diameter with the area?
Answers. 1. The formula for the area A as a function of the diameter d of a circle is given by A = π (d/2)^2.
How many diameters are in a circle?
Thus the diameter of the circle is twice as long as the radius. So, infinitely many diameters can be formed in the circle.

What is the diameter length of the crust?
Earth's crust is 5 to 70 km thick. Continental crust makes up the land on Earth, it is thicker (35 – 70 km), less dense and mostly made up of the rock granite. Oceanic crust makes up most of the ocean, it is thinner (5 – 7 km), denser and mostly made up of the rock basalt.
What is the diameter of the Earth’s mantle?
The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.
What is the radius and diameter of Earth?
The diameter of a circle is twice the radius, giving us a diameter for Earth of 12,756 km. Note: The Earth is almost, but not quite, a perfect sphere. Its equatorial radius is 6378 km, but its polar radius is 6357 km – in other words, the Earth is slightly flattened.
What is the radius of the earth in geography?
Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of nearly 6,378 km (3,963 mi) (equatorial radius, denoted a) to a minimum of nearly 6,357 km (3,950 mi) (polar radius, denoted b).

Which place is center of Earth?
In 2003, a refined result was yielded by Holger Isenberg: 40°52′N 34°34′E, also in Turkey, near the district of İskilip, Çorum Province, approx. 200 km northeast of Ankara. In 2016, Google Maps marked Isenberg's result of 40°52′N 34°34′ECoordinates: 40°52′N 34°34′E as the geographical center of Earth.
What’s the diameter of the sun?
865,370 miSun / Diameter Radius, diameter and circumference The sun is nearly a perfect sphere. Its equatorial diameter and its polar diameter differ by only 6.2 miles (10 km). The mean radius of the sun is 432,450 miles (696,000 kilometers), which makes its diameter about 864,938 miles (1.392 million km).
Is the sun bigger than the Earth?
At about 864,000 miles (1.4 million kilometers) wide, the sun is 109 times wider than Earth, and it accounts for more than 99.8 percent of the solar system's total mass. If it was a hollow ball, more than a million Earths could fit inside it.
