Solve the problem.A company packages its powdered iced tea mix in containers in the shape of a cylinder. The top and bottom are made of a plastic product that costs 3 cents per square centimeter. The side of the container is made of a cheaper material that costs 1 cent per square centimeter. The height of the cylinder can be found by dividing its volume by the area of its base. (i) If x is the radius of the base (in centimeters), write a rational expression in x whose values give the cost of each container, assuming that the capacity of the container is 90 cubic centimeters.(ii) Find the cost of a container whose base is 10 centimeters in diameter, using 3.14 as an approximation of ?. Round to the nearest cent, if necessary.
