Answer 1

Answer:

6.28 miles

Step-by-step explanation:

How far Michelle bike around the bicycle trail is the circumference or perimeter of bicycle trail.

This is given by:

$C = \pi \: d$

where d=2 miles is the diameter of the bicycle trail.

We substitute to get:

$C = \pi \: \times 2 = 2\pi$

$C = 6.28$

Therefore she travelled approximately 6.28 miles
