21120000 feet.
To determine how many feet are in 4,000 miles, we need to know the conversion factor between miles and feet.
There are 5,280 feet in a mile. So, to convert miles to feet, we can multiply the number of miles by 5,280.
Mathematically, the calculation would be as follows:
4,000 miles * 5,280 feet/mile = 21,120,000 feet
Therefore, there are 21,120,000 feet in 4,000 miles.
