Answer:

Distance covered by hula hoop in 44 rotations = 9671 cm

Explanation:

In the given question,

radius of the hula hoop (r) = 35 cm

and full rotation = 44

Now,

circumference of the hula hoop = 2
\pir

Then,

distance covered in one rotation = circumference of the hula hoop

distance covered in 44 rotations = 44 × circumference of the hula hoop

Distance = 44 × 2
\pir = 44 × 2 × 3.14 × 35 = 9671.2 cm

Distance covered by hula hoop in 44 rotations = 9671 cm

Answer:

distance covered in 44 full rotation = 9671 cm

Explanation:

It is given that radius of hula hoop is 35 cm

circumference of the hula hoop =
2\pi (radius)

=
2\pi (35)

=
70\pi

distance covered in one rotation = circumference of the hula hoop

=
70 \pi

distance covered in 44 full rotation =
44(70)\pi

=
3080\pi

we have
\pi =3.14

distance covered in 44 full rotation =
3080(3.14)

= 9671.2 cm

distance covered in 44 full rotation = 9671 cm ( rounding to nearest cm)
