The diameter of a bicycle wheel is 65 cm

How many revolutions are needed to make the bike travel 2km

C = pi * d

C = 3.14 * 0.65 m
C = 2.041 m

2,000 / 2.041 = 979.91 revolutions

Well, that depends on how much the bike hates walking. But in all seriousness, we can calculate the number of revolutions using the circumference of the wheel and the distance traveled.

The circumference of a circle is given by C = πd, where d is the diameter. So in this case, the circumference is approximately 65 cm x π.

Now, 2 kilometers is equal to 200,000 centimeters. To calculate the number of revolutions, we divide the distance traveled by the circumference of one revolution.

So the number of revolutions is approximately 200,000 / (65π) revolutions.

Don't worry, I'll spare you the actual math. Let's just say it's going to be a whole lot of spinning!

To find out how many revolutions are needed to make the bike travel 2 km, we can use the formula:

distance = circumference * number of revolutions

The circumference of a circle can be calculated using the formula:

circumference = π * diameter

Given that the diameter of the bicycle wheel is 65 cm, we can calculate the circumference as:

circumference = π * 65 cm

To find the number of revolutions required to travel 2 km, we need to convert the distance from km to cm, since the circumference is in cm. We know that 1 km is equal to 100,000 cm. Therefore, 2 km is equal to:

2 km = 2 * 100,000 cm = 200,000 cm

Now we can solve for the number of revolutions (N):

200,000 cm = (π * 65 cm) * N

Simplifying the equation:

N = 200,000 cm / (π * 65 cm)

Using the value of π as approximately 3.14, we can calculate N:

N = 200,000 cm / (3.14 * 65 cm)

N ≈ 969.325

Therefore, approximately 969.325 revolutions are needed to make the bike travel 2 km.

To find the number of revolutions needed to make the bike travel 2 km, we first need to calculate the circumference of the bicycle wheel using the given diameter.

The circumference of a circle can be found using the formula: Circumference = π * Diameter

Plugging in the given diameter of the bicycle wheel (65 cm), we have:

Circumference = π * 65 cm

Next, we need to convert the circumference to meters, since the distance given (2 km) is in meters.

1 meter = 100 cm

So, the circumference in meters would be:

Circumference (m) = (π * 65 cm) / 100

Now, we can calculate the number of revolutions using the formula:

Revolutions = Distance / Circumference

Given that the distance is 2 km, we convert it to meters:

2 km = 2000 meters

Therefore, the number of revolutions needed to make the bike travel 2 km is:

Revolutions = 2000 meters / Circumference (m)

You can calculate this value by plugging in the calculated circumference (in meters) into the formula.
