No, Jabir ibn Hayyan was a prominent Islamic alchemist and chemist known for his contributions to early chemistry, not for calculating the radius of the Earth. The Earth's radius was calculated by other scientists and mathematicians, such as Eratosthenes in ancient times.

How to calculate the circumference of the Earth?

To calculate the circumference of the Earth, you can use the formula C 2r, where C is the circumference, is a constant (approximately 3.14159), and r is the radius of the Earth. The average radius of the Earth is about 6,371 kilometers. Plug this value into the formula to find the circumference.


Can you calculate the volumes of the Earth and the Moon?

Based on what? If you know the radius, you can use the formula for a sphere - which is a good approximation in the case of Earth and Moon.


The mean raduis of the earth is 6.3710 to the power of 6mand that of the moon is 1.7410 to the power of 8cmfrom these data calculate a the ratio of the earth's surface are to that of the moon?

The ratio of the surface areas is (earth's radius/moon's radius)^2 where the radii are in the same units.This gives the answer as 13.40, approx.And, incidentally, the word is radius, not raduis!


What is the formula for calculating the mass of the Earth?

if g=9.8m/s, G=6.7*10-11Nm2kg-2,calculate the mass of earth, if the radius of the earth is approximately 64m


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 calculate earth's radius?

Eratosthenes (a greek) was the first person known to have accurately measured earth's radius. He did that about 250 BCE. The trick was to measure the length of the shadow cast by the library at Alexandria during the summer solstice, and knowing the distance between Alexandria and Cyene--a city on the Tropic of Cancer. A bit of trigonometry, and earth's radius falls right out.


The weight of the body on the surface of the is 250N. calculate its weight at distance equal to half of radius of the earth below the surface of earth. (radius of earth6400km)?

This is hard to calculate precisely, due to the fact that Earth's density increases towards the center. However, you make a simplified calculation, by assuming a uniform density. Just calculate the ratio of the volume (and therefore, of mass) of a sphere which has half the radius of the Earth, and calculate the gravitational attraction (once again, you only need a ratio, compared to the complete Earth) on that object.


How does Venus compare with the earth radius and mass?

Venus' radius = 0.95 of Earth's Venus' mass = 0.815 of Earth's

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?

Mercury's radius is what percent of Jupiter's radius?

Mercury's radius is 0.3825 that of Earth Jupiter's radius is 11.209 that of Earth So: (0.3825/11.209)*100 = 3.41 percent.
