3. A container in the shape of a (right) cylindrical can with an open top of volume 87 cm³ is to be painted. The cost for painting the base is 1$ per square centimeter, while the sides cost 2$ per square centimeter. Find the dimensions and the minimal cost of painting such a can. Hint: Surface area of a (right) cylinder = 27r² (area of bases) + 27rh (lateral area)
