Detailed explanation-1: -Complete answer: The average distance from the surface of the earth to its center is 6, 371 km or 3, 959 miles.
Detailed explanation-2: -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). Planet Earth is older than the core. When Earth was formed about 4.5 billion years ago, it was a uniform ball of hot rock.
Detailed explanation-3: -If the Earth Stood Still To model this hypothesis, a value of 6, 371, 146 meters-the distance from the earth’s center indicates the approximate elevation of the sea level on the reference ellipsoid-was specified to separate water from land.
Detailed explanation-4: -Earth’s circumference (the distance all the way around the equator) is 24, 901 miles (40, 075 kilometers). Its diameter (the distance from one side to the other through Earth’s center) is 7, 926 miles (about 12, 756 kilometers).
