    The diameter of the floor is 6 yards

    Step-by-step explanation:

    Here, we are to calculate the diameter of a circular floor that has a circumference of 18.84 yards

    Mathematically,

    C = π * D

    where C is the circumference

    Plugging the values of the circumference, we have;

    18.84 = 22/7 * D

    7 * 18.84 = 22D

    D = (7 * 18.84) / 22 = 5.99 which is approximately 6 yards
