Answer 1

Hello!

To find the circumference, you multiply the diameter by pi. We will do so below.

2.5$\pi$≈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!

Answer 2

The circumference would be 7.85

And b would be 672.611465 because each time you divide by 7.85 ft
