Diameter of the reel is 3cm
circumference(C) of the reel = TTD = 3TT cm
No.of times the cotton go around the reel= length of the cotton/C
= 0.91 m / 3TT cm
= 91cm / 3x 3.14 cm---------------> 100cm =1m
= 9.66
so,the cotton will go around (approximatly)10 times around the reel.
If the length of the cotton is 91m which is 9100cm
then,
No.of times the cotton go around the reel= length of the cotton/C = 9100 /3x3.14
=966
Answer will be 966 times
