Answer 1

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.
