Respuesta :

The hula hoop rolls 879 cm.



Answer:

879.2 cm

Step-by-step explanation:

The distance around the hula hoop is given by the circumference.  The formula for the circumference of a circle is

C = 2πr

Using 3.14 for pi and our value of 35 as r, we have

C = 2(3.14)(35) = 219.8

For 4 rotations, this gives us a distance of

219.8(4) = 879.2 cm
