Yup. The engineer wants the answer so h e can go on to design the system the red rubber ball is part of. He learned in school how to calculate it but his boss just wants that final design and has no interest in paying the engineer for red rubber ball calcs. (I was that engineer who would write a routine to do approximate integrations to calculate volumes of irregular red rubber balls, those balls for which the tables don't work because they are not round. Routines that were not spot on accurate but good enough and took minutes, not hours or hours, not days.)
