how far will the bike travel if the wheel makes 5 revolutions? the diameter is 40cm. show work
The bike moves forward pi*D for each revolution. Multiply that by 5.
You do the work
3.14 * 40 = 125.6*5= 628cm
answer= 628cm
To find out how far the bike will travel when the wheel makes 5 revolutions, you can use the formula:
Distance = Circumference × Number of revolutions
First, let's find the circumference of the wheel. The circumference of a circle can be found using the formula:
Circumference = π × Diameter
Given that the diameter of the wheel is 40 cm, we can calculate the circumference:
Circumference = π × 40 cm
Circumference ≈ 3.14 × 40 cm
Circumference ≈ 125.6 cm
Now, we have the circumference of the wheel, which is approximately 125.6 cm. We can proceed to calculate the distance traveled:
Distance = Circumference × Number of revolutions
Distance = 125.6 cm × 5 revolutions
Distance = 628 cm
Therefore, the bike will travel a distance of 628 cm when the wheel makes 5 revolutions.
