the diameter of a biycle wheel is 49 cm. how far will it travel in 50 revolutions?
C = pi * d
Multiply the circumference by 50.
To find how far a bicycle wheel will travel in a given number of revolutions, you can use the formula:
Distance = Circumference of the wheel * Number of revolutions
First, we need to find the circumference of the wheel. The circumference of a circle is calculated using the formula:
Circumference = π * Diameter
Given that the diameter of the bicycle wheel is 49 cm, we can substitute this value into the equation:
Circumference = π * 49 cm
Now, let's calculate the circumference of the wheel:
Circumference = 3.14 * 49 cm (Note: π is approximately equal to 3.14)
Circumference ≈ 153.86 cm (rounded to two decimal places)
Now that we have the circumference, we can calculate the distance traveled by multiplying it by the number of revolutions:
Distance = 153.86 cm * 50 revolutions
Distance = 7,693 cm (rounded to the nearest whole number)
Therefore, the bicycle wheel will travel approximately 7,693 cm (or 76.93 meters) in 50 revolutions.
