Each wheel on Harley's bike has a radius of 60 cm. How many revolutions does each bike make when Harley bikes 500 cm?
A. 500/120pi
B. 1000/120pi
C. 50000/120pi
D. 100000/120pi
x = total turns
c = πd
60 cm = 0.6 m
since the radius 0.6 m, the diameter is 1.2.
turns * circumference = revolutions
that becomes:
x * 1.2π=500
solve it yourself, but it becomes x = 1250/3π
since all the denominators have 120π we can do proportions
1250/3π = y/120π
(y is another random variable)
solve the proportion your own
y =50000
that becomes 50000/120π, so your answer is c
Hey R, I think you meant total turns * circumference = total distance
To determine the number of revolutions each wheel makes when Harley bikes a distance of 500 cm, we can use the formula:
Number of revolutions = Distance / Circumference
First, we need to find the circumference of each wheel. The circumference of a circle can be calculated using the formula:
Circumference = 2 * π * radius
Given that the radius of each wheel is 60 cm, we can calculate the circumference using the above formula:
Circumference = 2 * π * 60 cm
Circumference = 120π cm
Now, we can substitute the values into the formula to find the number of revolutions:
Number of revolutions = 500 cm / 120π cm
Simplifying the expression:
Number of revolutions = (500 / 120π)
To improve readability, we can rationalize the denominator by multiplying both the numerator and denominator by π:
Number of revolutions = (500π / 120π)
Now, we can simplify the expression further:
Number of revolutions = 500 / 120
Therefore, the correct answer is:
A. 500 / 120π
well, the circumference is C = 2πr = 120π
so, the revolutions in 500cm can be found using
500cm * 1rev/120πcm = 500/120π rev = (A)
