Ember Labs executives are presented with two blueprints for a new right circular cylinder water tower as an addition to the complex. This tower will capture rainwater to be used to irrigate the facilities grass fields, tree and plant life, as well as purified drinking water for the people who work at the SHED. The Ember Labs' executives were presented with two design proposals with the following parameters: the first one has a base diameter of 7 cm and a height of 9 cm, and a second one has a base diameter of 9 cm and a height of 13 cm.
A. If the scale for the blueprint drawings is 2 centimeters to 8 yards, what is the difference in cost (stated as a percentage) between the two designs if they use the same hybrid steel the project uses for the solar panel frames? Assume that they will only use the material for the exterior of this building.
B. Assume the weather will contribute an average of 6 ounces of rainwater to the water tower per day, how long will it take to fill each of the towers? What is the difference (as a percentage) between the total amount of water the towers can collect?
