Answer 2

The distance the hula hoop rolls in 4 full rotations is 880 cm.

Explanation:

Given : Allison is rolling her hula hoop on the playground. The radius of her hula hoop is 35 cm.

To find : What is the distance the hula hoop rolls in 4 full rotations?

Solution :

The radius of her hula hoop is 35 cm.

Perimeter of hoop =
`2 \pi r`

Distance of hoop in 1 rotation =
`2 * (22)/(7) * 35 =220\ cm`

Distance covered in 4 rotations =
`220 * 4 = 880\ cm`

Hence, the distance the hula hoop rolls in 4 full rotations is 880 cm.
