Digital bits on a 12.0-cm diameter audio CD are encoded along an outward spiraling path that starts at radius R1=2.5cm and finishes at radius R2 = 5.8 cm . The distance between the centers of neighboring spiral-windings is 1.6?m(=1.6×10^?6m).

Determine the total length of the spiraling path. [Hint: Imagine "unwinding" the spiral into a straight path of width 1.6?m, and note that the original spiral and the straight path both occupy the same area.]
