I think you multiply pi by 2.5 is about 7.5 so the circumference is about 7.5


And next i think you divide 7.5 by 5280 and so you get 39,600

Answer:

a) 2.5π, b) ≈673 times

Explanation:

diameter = 2.5

circumference = diameter*π

circumference = 2.5π

5280/2.5π

≈5280/2.5*3.14

≈5280/7.85

≈672.6, ≈673
