Answer:

5,538.96 in

Step-by-step explanation:

A=π r^2

Remember r^2 is r * r.

r^2 = 42*42= 1,764

A= 3.14 * 1,764 = 5,538.96in

A = pi r^2

We know the radius is 42 and pi is approximated by 3.14

A = 3.14 * 42^2

A =5538.96 in^2

Allison is rolling her hula hoop on the playground. The radius of her hula hoop is 35 cm. What is the distance the hula hoop rol
lidiya [134]

Answer:

Distance covered by hula hoop rolls in 4 full rotations is 880 cm .

Step-by-step explanation:

Formula

Perimeter\ of\ a\ circle = 2\pi r

Where r is the radius of the circle.

As given

Allison is rolling her hula hoop on the playground.

The radius of her hula hoop is 35 cm.

r = 35 cm

\pi = \frac{22}{7}

Putting the value in the formula

Perimeter\ of\ a\ hula hoop = 2\times \frac{22}{7} \times 35

                                             = 220 cm

As given

The hula hoop rolls in 4 full rotations.

Distance covered by hula hoop rolls in 4 full rotations =  220 × 4

                                                                                          = 880 cm

Therefore the Distance covered by hula hoop rolls in 4 full rotations is 880 cm .
