Tim has a collection of square tiles of various sizes, each of which has an etched

quarter circle with radius equal to the side length of the tile. Tim arranges eight

tiles as shown. If the two smallest tiles each have side length 10 cm, what is the

length of the resulting spiral formed by the tiles’ etchings? Express your answer

in terms of π.
