To solve this problem, we need to determine the circumference of the bicycle wheel and then calculate how many revolutions it would take to cover a distance of 46.2km.

The circumference of a circle is calculated using the formula: C = πd, where C is the circumference, π is approximately 3.14, and d is the diameter of the circle.

So, the circumference of the bicycle wheel is:

C = π * 4.9m = 3.14 * 4.9 = 15.386m

Now, we can calculate how many revolutions are needed to cover a distance of 46.2km:

Distance to be covered = 46.2km = 46,200m
Number of revolutions = 46,200m / 15.386m = 3000 revolutions

Therefore, the bicycle wheel of diameter 4.9meters would need to make 3000 revolutions to cover a distance of 46.2km.
