The distance traveled by the hula hoop in 4 rotations is equivalent to four times the circumference of the hula hoop.
Use the following formula for the circumference:
C = 2·π·r
where π = 3.14 and r = 35 cm is the radius. Replace these parameters inot he formula for C:
C = 2(3.14)(35 cm)
C = 219.8 cm
next, remind the distance traveled for 4 rotations in four times C:
distance traveled = 4·C = 4(219.8 cm) = 879.2 cm
