    879.2 cm

    Step-by-step explanation:

    The distance around the hula hoop is given by the circumference. The formula for the circumference of a circle is

    C = 2πr

    Using 3.14 for pi and our value of 35 as r, we have

    C = 2 (3.14) (35) = 219.8

    For 4 rotations, this gives us a distance of

    219.8 (4) = 879.2 cm
