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.

Find the exact solution of the system of equations of x^2+y^2-4x-6y+4=0 and x^2-4x-3y+4=0

gavmur [86]

We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0
y^2-3y=0
y(y-3)=0
y1=0 -----------y2=3
