Smoking With Exponents: Geometrically the WSM is a sphere bisected by a cylinder. As most LTHers will no doubt recall from their time in Jesuit detention, the area of a circle changes by the square of the radius, the volume of a sphere changes with the cube of the radius (times 4/3), and a cylinder "only" by the radius squared (times height). So, by higher math, we see that the grill area of the Greater Smoker is 49% larger than the Lesser Smoker, while interior volume is increased by 72%, even though the radius is only 21.6% bigger and the barrel a measly three inches longer. So, almost half again as much space to cook, but almost three quarters the volume to heat. All from a two inch bump in radius and a modest increase in height. Extra credit assignment: for the interested (and intrepid) pitperson, determine the general volume equation of an WSM and calculate its first derivative with respect to r.
