Answer 1

Answer:

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

Step-by-step 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 =$2 \times \frac{22}{7} \times 35 =220\ cm$

Distance covered in 4 rotations =$220 \times 4 = 880\ cm$

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