how many full revolutions does a car tire with a diameter of 25 inches make when the car travels one mile?
The circumference of the tire can be found using the formula: circumference = π*diameter
Circumference = 3.14159 * 25 inches = 78.54 inches
There are 12 inches in a foot, and 5280 feet in a mile, so:
78.54 inches / 12 = 6.545 feet
1 mile = 6.545 feet * 5280 = 34,559.4 feet
Now, we can find the number of revolutions:
34,559.4 feet / 78.54 inches = 440 revolutions
Therefore, the car tire with a diameter of 25 inches would make 440 full revolutions when the car travels one mile.
