A bicycle wheel has a diameter of 65cm. What is the length of one revolution of the wheel?
C = πd = 65π = 204.2 cm

To find the length of one revolution of a bicycle wheel, you need to calculate the circumference of the wheel.
The circumference of a circle can be found using the formula:
C = π * d
Where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and d is the diameter of the circle.
In this case, the diameter of the bicycle wheel is given as 65 cm.
So, the circumference of the bicycle wheel can be calculated as:
C = π * 65 cm
Now, plug in the value of π, which is approximately 3.14159, and multiply it by the diameter of the wheel:
C = 3.14159 * 65 cm
Using a calculator, the circumference can be calculated as follows:
C ≈ (3.14159) * 65
C ≈ 204.203 cm
Hence, the length of one revolution of the bicycle wheel is approximately 204.203 cm.
