Answer: 880 cm
Explanation:
Given: Radius of the hula hoop = 35 cm
Hula hoop is circular in shape
Then, Circumference =
, where r = radius
Now , Circumference of hula hoop =

Now , the distance the hula hoop rolls in 4 full rotations = 4 Ă— (Circumference of hula hoop)

Hence, the required distance = 880 cm
