    87.9 feet

    Step-by-step explanation:

    circumference = 2 (π) (r)

    c = 2 (3.14) (14)

    c = 87.92

    round to nearest tenth: c = 87.9

    Formula for the circumference of a circle:

    C = 2πr (C = circumference π (pi) = 3.14 ... r = radius)

    You know:

    r = 14 ft

    π = 3.14 So substitute/plug it into the equation

    C = 2πr

    C = 2 (3.14) (14)

    C = 87.92 Round to the nearest tenth

    C = 87.9 ft
