Question

A bicycle trail in the shape of a circle has a diameter of 3 miles. Michelle biked around the trail 4 times. About how far did Michelle bike?

Answer 1

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.
