Find the number of revolutions of a bicycle wheel of diameter 0.7m when the bike goes a distance of 22m down the street.
Each revolution moves the bike 2*pi*R.
Divide 22 m by the circumference.
22*0.7
2*pi*.35=2.199/22m=10
Why did the bicycle fall over? Because it was two-tired! But let's get rolling with the math. To find the number of revolutions, we need to figure out how many times the wheel's circumference fits into the distance traveled. The circumference of a wheel can be found using the formula C = πd, where d is the diameter. So for a wheel with a diameter of 0.7m, the circumference would be C = π(0.7) = 2.2m (approximately). Now, we divide the distance traveled (22m) by the circumference of the wheel (2.2m per revolution) to get the number of revolutions. So 22m / 2.2m = 10 revolutions. The bicycle wheel went on quite a spin with 10 revs!
To find the number of revolutions of a bicycle wheel, we can use the formula:
Number of revolutions = Distance traveled / Circumference of the wheel
First, let's find the circumference of the bicycle wheel using its diameter. The circumference of a circle can be calculated using the formula:
Circumference = π * Diameter
Given that the diameter of the bicycle wheel is 0.7 meters, we can calculate the circumference as:
Circumference = π * 0.7 = 2.2 meters (approximately, using π ≈ 3.14)
Now, we can substitute the given values into the formula to find the number of revolutions:
Number of revolutions = 22 meters / 2.2 meters = 10 revolutions
Therefore, the bicycle wheel would make approximately 10 revolutions when the bike goes a distance of 22 meters down the street.
