Area: A = 2 ? r h + 2 ? r Volume: V-?r2h+(23) ? r Cost: C-400 (2 ? r h) + 800 (2 ? r 2) Assume a "small" tank with a volume of V- Then, h=1/P-as) r Create a radius vector r over the range of 0.5 to 1.5 with a step size of 0.01. Then, create vectors for height (h) and cost (C) from the formulas above. Don't forget the dot (".") operators where needed. h- Enter the statements below to plot the cost as a function of radius. >>plot(r,C), grid Sketch the plot below. Fill in the scale values on the y-axis. Estimate from the plot the radius r resulting in minimum cost. rrL (for minimum cost) Use MATLAB's min function below to verify minimum cost observed on the graph. min(C) ans (minimum cost) over
