Question

You ride your bicycle 40 meters. How many complete revolutions does the front wheel make?

Answer 1

First, we convert the given radius of the wheel to meters giving us an answre of 0.325 m. Then, we calculate for the circumference.
                                           C = 2πrr
Substituting,
                                          C = 2π(0.325 m) = 2.04 m
Then, we have a road that is 40 m long, the number of complete revolutions is,
                                      n = 40/2.04 m = 20
