In this exercise we have to calculate the rotation number, so we find that:
For max diameter 3 rotations for min diameter makes 11 rotations.
Knowing that it is a circle we will use the rotation formula as:
[tex]C=\pi d[/tex]
Knowing that some information was given in the statement, we have:
Substituting the known information in the formula, we have:
[tex]C=3.14(60) = 188.4[/tex]
So now we have to divide by the total number, so the rotations will be:
[tex]600/188.4= 3 \ rotations[/tex]
Putting the value of the smaller diameter, we have:
[tex]C= 3.14(2*9) = 3.14(18) = 56.52[/tex]
So now we have to divide by the total number, so the rotations will be:
[tex]600/56.52=11 \ rotations[/tex]
