    The total length of the border is 31.4 yards rounded to the nearest tenth of a yard

    Step-by-step explanation:

    The formula of the circumference of a circle is C = 2πr, where r is the radius of the circle

    Jason used wire fencing to form a border around a circular region in his back yard

    That means the length of the wire is equal to the circumference of the circular region

    ∵ The radius of the circular region was 5 yards

    ∴ r = 5 yards

    ∵ C = 2πr

    - Substitute r by 5

    ∴ C = 2π (5)

    ∴ C = 31.41592654 yards

    - Round it to the nearest tenth of a yard

    ∴ C = 31.4 yards

    ∵ The length of the wire is equal to the circumference of

    the circular region

    ∴ The length of the wire is 31.4 yards

    The total length of the border is 31.4 yards rounded to the nearest tenth of a yard
