You are given a feasible region. Find the maximum and minimum (if they exist) for the given objective function. (If an answer does not exist, enter DNE.) 16x 26y Z = (2,7) (0,5) y (6,2) (5,0) (0,0) X X Your answer cannot be understood or graded. More Information maximum XYour answer cannot be understood or graded. More Information minimum Enter an exact number.

You are designing a cylindrical barrel that can hold 16π m3 of crude oil. Find the radius r and heighth of the barrel that uses the least amount of material possible.(Hint: The surface area of a cylinder is S = 2πr2 + h(2πr), and its volume is V = πr2h.)(a) Draw a diagram representing this situation.(b) Write the objective and constraint functions.Objective:Constraint:(c) Use the constraint function to write the objective as a function of one variable.(d) Determine the radius and height for the absolute minimum surface area

I have seen I have seen ways for c and d. Which is right?
