A beverage company plans to produce cylindrical cans that must contain exactly 1000 cm3 of liquid. The aluminum for the curved side surface costs \0.02persquarecentimeter,whilethealuminumforeachcircularendcosts0.03 per square centimeter.
(a) Write an expression for the total manufacturing cost C of a single can in terms of the radius r (cm) and height h (cm).
(b) Eliminate one variable using the fixed-volume requirement and rewrite C as a function of a single variable.
(c) Determine the radius and height that minimize the cost of one can. Clearly indicate the test you use to confirm that your result is a minimum.
(d) Using your optimal dimensions, compute the minimum possible cost per can, rounded to the nearest cent, and explain its significance for budgeting.
a. Part (a) -- formulate C(r,h)
b. Part (b) -- express C in one variable
c. Part (c) -- locate and justify the minimum
d. Part (d) -- interpret the minimized cost
