Question

the diameter of a bike wheel is 25 inches. If the wheelmakes 20 Complete rotations, how far does the bike travel?

Answer 1

1571 in

Explanation:

Given data

Diamter= 25 in

radius= 25/2= 12.5in

Circumference= 2πr

substitute

C=2*3.142*12.5

C=78.55in

In 1 revolution the bike will travel 78.55in

in 20 revolutions the bike will travel

=78.55*20

=1571 in
