Consider the extrusion of a cylindrical billet.  Assume the billet to have a length of 0.3m and a diameter of 0.15m.  This is extruded into a cylindrical product that is 0.03m in diameter and 7.5m long (a reduction ratio of 25).  Neglecting the areas on the two ends, compute the ratio between the product surface area (wraparound cylinder) and the surface area of the starting billet. How would this ratio change if the product were a square with the same cross-sectional area as that of the 0.03m diameter circle?

Question

Consider the extrusion of a cylindrical billet.  Assume the billet to have a length of 0.3m and a diameter of 0.15m.  This is extruded into a cylindrical product that is 0.03m in diameter and 7.5m long (a reduction ratio of 25).  Neglecting the areas on the two ends, compute the ratio between the product surface area (wraparound cylinder) and the surface area of the starting billet.

How would this ratio change if the product were a square with the same cross-sectional area as that of the 0.03m diameter circle?
