Step-by-step explanation:
How far Michelle bike around the bicycle trail is the circumference or perimeter of bicycle trail.
This is given by:
[tex]C = \pi \: d[/tex]
where d=2 miles is the diameter of the bicycle trail.
We substitute to get:
[tex]C = \pi \: \times 2 = 2\pi[/tex]
[tex]C = 6.28[/tex]
Therefore she travelled approximately 6.28 miles
