Answer:

Step-by-step explanation:

The circumference of a circle is the distance around the outside of a circle. If we can find the circumference of the wheel, we can find out how far Elena can travel when her wheel turns one time.  If we can find out how far she travels in one wheel turn, we will multiply that distance by 840 to see how far she travels when her wheels turn 840 times.

[tex]C=2\pi r[/tex] and

C = 2(3.14)(.25) so

C = 1.57 m

1.57 x 840 = 1318.8 meters
