If the mine is 6m, calculate how far the cage will drop for each single rotation of the drum ,use the formula C=2
see the similar questions below, and next time, try to make sure your question includes all the relevant data.
As written, it's garbage.
Formula
*C=(2pie)r
*diameter =6m
Formula to calculate radius
*r=number of diameter/2
r=6/2
=3
Therefore c=(2pie)(3)
=18,85cm
