    Given:

    Circular racetrack with a diameter of 1/2 mile

    Find: how far does a car travel in one lap around the track?

    We need to find the circumference of the racetrack.

    Circumference is multiplying pi to the diameter of the racetrack.

    Circumference = 3.14 * 1/2 mile

    Circumference = 3.14/2 mile

    Circumference = 1.57 miles rounded to the nearest tenth is 1.60 miles.
