Answer 1

Answer: 880 cm

Step-by-step explanation:

Given: Radius of the hula hoop = 35 cm

Hula hoop is  circular in shape

Then, Circumference = $2\pi r$ , where r = radius

Now , Circumference of hula hoop = $2\times \dfrac{22}{7}\times35=220\ cm$

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

$= 4 \times 220=880\ cm$

Hence, the required distance = 880 cm
