Length of the creeper

There is a tree with a trunk that is a perfect cylinder. The circumference of the base being 6ft. The height of the cylinder is 8ft. A creeper wraps around the trunk, rising uniformly from the ground to the top, and in doing so, makes exactly one turn (so the end point is on the same vertical line as the starting point).

What is the length of the creeper?
