There are 5280 feet in one mile. Therefore, 3963 miles is equal to 3963 x 5280 = 20924640 feet.
There are 1609.344 metres in one mile. Therefore, 3963 miles is equal to 3963 x 1609.344 = 6377830.272 metres.
There are 1.609344 kilometres in one mile. Therefore, 3963 miles is equal to 3963 x 1.609344 = 6377.830272 kilometres.
Earth's radius is a little less than 4000 miles.
It is 3963 miles to the center of the Earth, or the core.
If you do this 7107 - 3144 = 3963 3963 - 2000 = 1963 1963 IS THE ANSWER
The equitorial diameter of the Earth (distance from one side of the Earth to the other at the equator) is about 7,926 miles. So the circumference is 7,926 * pi = 24900.2633 miles. Divide 7,926 by 2 to get the radius: 3963 miles. Add six feet to this radius: 3963 mi + (6 ft / 5280 ft) = 3963.001136 miles. The new circumference is 3963.001136 x 2 x pi = 24900.27051 miles. Subtract for the difference: 24900.27051 - 24900.2633= 0.00721 miles or 38 feet.
The Earth is not a perfect sphere, so the distance to the center of the Earth varies from 6378 km (3963 miles) at the equator to 6357 km (3950 miles) at the poles.
6378 km I think that is about 3963 miles?
It is 3963 miles to the center of the Earth, or the core.
3 miles = 15,840 feet 6 miles = 31,680 feet
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.
Three miles = 15,800 feet.
