Answer:

Option C is correct.


38 miles

Explanation:

Let x be the distance cover by Michelle

Given:

A circle diameter is 3 miles.

And Michelle biked around the trail 4 times.

We know that

The circumference of a circle.

circumference =
2\pi r----------(1)

where
r=(Diameter)/(2)


r=(3)/(2) \\r=1.5 miles

Put
\pi =3.14 and r value in equation 1.


circumference = 2* 3.14 1.5


circumference = 9.42 mil;es

The circumference of a circle is 9.42 miles.

And Michelle biked 4 times, that is equal to 4
* circumference.


x = 4* 9.42


x = 37.65 miles.

That is equal to 38 miles.

Therefore, Michelle biked around 4 trail is 38 miles.
