Use 3.14 as pi.
the diameter of a bicycle wheel is 0.7 metre. determine the number of complete revolutions by the wheel of the bicycle travels 440 metres.
First, we need to find the circumference of the bicycle wheel using the formula:
Circumference = pi x diameter
Circumference = 3.14 x 0.7 = 2.198 metres
Next, we can use the distance traveled (440 metres) and the circumference of the wheel to determine the number of revolutions using the formula:
Number of revolutions = Distance traveled / Circumference
Number of revolutions = 440 / 2.198 = 200.18
Therefore, the wheel of the bicycle will make approximately 200 complete revolutions.
To determine the number of complete revolutions the bicycle wheel travels, we can use the formula:
Distance traveled = Circumference of the wheel x Number of revolutions
Let's start by finding the circumference of the wheel using the given diameter.
1. The diameter of the wheel is given as 0.7 meters.
So, the radius of the wheel will be half of the diameter, which is 0.7/2 = 0.35 meters.
2. The formula to calculate the circumference of a circle is:
Circumference = 2 x pi x radius
Using the value of pi as 3.14, we can calculate the circumference of the wheel:
Circumference = 2 x 3.14 x 0.35
= 6.28 x 0.35
= 2.198 meters (approximately)
Now, we can find the number of complete revolutions by rearranging the formula:
Number of revolutions = Distance traveled / Circumference
3. The given distance traveled is 440 meters.
Using the calculated circumference of the wheel, we can find the number of revolutions:
Number of revolutions = 440 / 2.198
= 200 (approximately)
Therefore, the bicycle wheel will make approximately 200 complete revolutions while traveling a distance of 440 meters.
