Problem 208 — The whole can be the sum of too many parts, as this month’s problem by Bruno Fria of Denver demonstrates.
High in a corner office of the Peenpoynt Micro Robotics Laboratory, an after- hours meeting was underway.
“Precision is what counts here!” stated Dr. Peenpoynt, Ph.D, D.D., D.D.S., M.D., “and we’re way behind deadline! Our latest etching tool features a stainless steel sphere inside a cylinder with a pointed top. Due to my staff not having my expertise and experience, I’ve worked out the dimensions in inches as follows (See sketch.). I’ve gone ahead and ordered stainless steel balls with 0.400-in. diameters.”
Compute the largest-diameter sphere that can fit inside the pointed cone. Will Peenpoynt have to recalculate and reorder?
