This is probably pretty simple for a lot of you, quick help would be much appreciated.



"A woman was shopping for toilet tissue. She saw a new brand selling packs of four rolls with 240 sheets per roll. She knew the tissues were 14 cm long and estimated the diameter of the tolls to be 11 cm, wound around cardboard cylinders of diameter 4cm. At first she was concerned that the tissues were would onto the roll in a spiral with increasing radius, but she eventually found her way around this problem and found the tissues thickness.
How thick was the tissue?
About how many turns of tissue paper are on each roll?"

Thank you!
