Answer
I think the answer is sqrt(581) as height is 15 and circumference of cylinder is 16 , one can open the cylinder into a rectangular sheet and the distance traveled by the spider would be the diagonal which would be sqrt(15^2+16^2)
Answer
sqrt t(381)
As the spiral is the diagonal of the rectangle formed when cylinder surface is cut open
