You ride your bicycle 40 meters. how many complete revolutions does the front wheel make?
32.5 cm
the bicycle makes complete revolutions.

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
