Omar races his bicycle for 152m. A wheel of his bicycle turns 38times as the bicycle travels this distance. What is the diameter of the wheel?
N*pi*D = 152 m
N is the number of turns (38)
Solve for D
D = 1.27 meters
Most bicycles have diameters less than this.. more like 0.68 meters
Basically... yeah.
To be more consise...
Number of turns = N
Pi = Pi
N times Pi = Diamater
Thats how you do it ;)
To find the diameter of the wheel, we can use the formula: Circumference = π * Diameter.
In this case, we know that the bicycle travels 152m and that the wheel turns 38 times.
First, let's find the distance covered with each wheel rotation:
Total distance covered = 152m
Number of wheel rotations = 38
Distance covered with each wheel rotation = Total distance covered / Number of wheel rotations
Distance covered with each wheel rotation = 152m / 38 = 4m
Next, we can calculate the circumference of the wheel using the distance covered with each wheel rotation:
Circumference = Distance covered with each wheel rotation
Circumference = 4m
Finally, we can use the formula Circumference = π * Diameter to find the diameter of the wheel:
Diameter = Circumference / π
Diameter = 4m / π ≈ 1.27m
Therefore, the diameter of the wheel is approximately 1.27 meters.
