Answer:
A single rotation accounts for the circumference of the mine winch drum:
from formula:
[tex]circumference = 2\pi r[/tex]
r » radius.
but r = 2 × diameter.
therefore; radius, r = 2 × 6 = 12 m
[tex]c = 2 \times 3.14 \times 12 \\ { \underline{ \underline{ \: \: circumference = 75.36 \: m \: \: }}}[/tex]
[ considering π to be 3.14 ]
