A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 4ft and a radius of 7ft. The tank will be made from metal (including its top and bottom). Suppose the total cost of the metal will be $18,858.84. How much will the metal cost per square foot? Use 3.14 for π, and do not round your answer.
