This number is remarkably close to modern calculations which put Earth’s circumference at 40,075 km (25,000 miles). The example above was done by my own students several years ago and shows a value within 4% of the true size of the Earth – pretty good for kids using some string and a protractor! How close will your students get! Discussion Questions Eratosthenes determined the Earth's circumference using basic geometry in 240 BC. Measured around the poles, the circumference is 40,007734 mi). It is measured along the Equator and at the poles, with different results. project zomboid free host What is Earth diameter and circumference?. However, the distance between Saturn and Earth varies based upon where both planets are in their orbits around the sun Earth’s crust is composed of iron, oxygen, silicon and magnesium. 989 x 10 30 kilograms, about 333,000 times the mass of the Earth. This estimate was only 100 miles off the actual circumference of 24,900 miles!

Nov 21, 2024 · Mars has a diameter of 6,792 km (4,220 miles); the planet’s circumference around the equator is 21,326 km (13,300 miles). The actual circumference of the Earth is 24,900 miles. tire and lube heaven at walmart discover hours that fit This method was very simple yet accurate, requiring just four measurements in all to be taken and then applying a trigonometric equation to arrive at the solution. The height above sea level of the … Eratosthenes Calculates the Circumference of the EarthOverviewThe measurement of distance became increasingly important to ancient and classical civilizations as their territorial and cultural horizons expanded. 863 km … Earth radius at sea level is 6378191 mi) at the equator752 km (3949. 621371, resulting in around 24,901 miles. game of thrones logo vector1 To calculate a circle’s diameter from its circumference, one should divide the circumference by the constant pi, which is an irrational number approximately equal to 3 The moon is not bigger than the Earth as it has a diameter of approximately 2,159 square miles, which is about one-quarter of the size of Earth. One of the many differences between the Earth and the moon is simply that the Earth is a planet and the moon orbits the Earth as its satellite. Thus, if you’re moving at a speed of about 100 km per hour (62 miles per hour), it will take you about nine days to travel around the planet's equator. The orbital speed of Earth averages about 29. The equatorial circumference is approximately 24,900 miles (40,075 km).
