    central angle is 1.55 rad

    Explanation:

    Given data

    radius = 14 feet

    length = 9 ft

    to find out

    radian measure of the central angle

    solution

    we know here arc length and radius

    so we will apply here formula for central angle that is

    radius = arc * ∅

    ∅ = radius / arc

    put here all these value

    ∅ = 14 / 9

    ∅ = 1.55 radian

    so central angle is 1.55 rad
