Answer:

37.68 miles

Explanation:

To solve this problem, we first need to find the circumference of the bicycle trail. The formula for the circumference of a circle is as follows:

$C=\pi d$

d = diameter

We know that the diameter of the bicycle trail is 3 miles. Lets plug in the values:

$C=\pi (3)$

C=9.42

The last step is to multiply 9.42 by 4 since Michelle biked around the trail 4 times.

x=9.42(4)

x=37.68

Michelle biked for 37.68 miles.
