Hello!
To find the circumference, you multiply the diameter by pi. We will do so below.
2.5≈7.85
a. 7.85 feet
___________________________________________________
To find how many rotations it will take to travel a mile, we will need to divide our mile by our circumference.
5,280/7.85≈672.61
b) 672.61
I hope this helps!
