What is the distance the hula hoop rolls in 4 full rotations?

879.65

Step-by-step explanation:

Givens

r = 35 cm

pi = 3.14

Formula

Circumference = 2*pi*r

Solve for 1 loop

C = 2*pi * r

C = 2 * 3.14 * 35

C = 219.9 cm for 1 loop

Solve for 4 loops

1 loop gives 219.9 cm distance that will be covered.

4 loops = x

1/4 = 219.9/ x       Cross multiply

x = 4 * 219.9         Combine on the right.

x = 879.65 cm
