Question

Each tire of a bicycle has a diameter of 26 inches. If you start pedaling and the tires make 10 complete rotations, how far has the bicycle traveled?
I'm pretty sure the answer is 3,265.6 inches, but I'm also pretty sure I'm wrong Pls help

Answer 1

The circumference (perimeter) of the tire is 2 x π x r (radius= half of the diameter):

So one complete rotation is equivalent to the perimeter that is 2 x 13 x 3.1459

= 81.68 inches & if he competed 10 rotation that means he run for 10 x 81.68 ===> 816.8 In
