how many turns must a bicycle wheel of a radius 0.5 m make to travel a distance of 100 m
Circumference = pi * d
C = 3.14 * 1
C = 3.14
100/ 3.14 = 31.8
To determine the number of turns a bicycle wheel must make to travel a distance of 100 m, we need to use the formula:
Distance = Circumference * Number of Turns.
The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * Radius.
Given that the radius of the bicycle wheel is 0.5 m, we substitute this value into the circumference formula:
Circumference = 2 * π * 0.5 = π meters.
Now, we can rearrange the first formula to solve for the number of turns:
Number of Turns = Distance / Circumference.
Plugging in the values we have:
Number of Turns = 100 m / π meters.
Now, we can calculate the number of turns:
Number of Turns = 100 / π ≈ 31.83 turns.
Therefore, a bicycle wheel of a radius 0.5 m must make approximately 31.83 turns to travel a distance of 100 m.
