Q3 Answer question Q3(a) - Q3(h) based on the information given in Figure Q3. A building surveyor has assigned you to write an application that calculates the total labour cost of building a cylinder water tank for an office building. To calculate the labour cost, you multiply the volume of the tank ( x radius x height) by the price per cubic metre of tank. For example, the volume of tank with 10 metres radius and 15 metres height is 4,710 cubic metres. To build the tank with labour cost of RM20 per cubic metre would result in total labour cost of RM94,200.00 (20.00x4,710). First, you should create a class named CylinderTank that has two fields: one for the radius of the tank and one for the height of the tank. The CylinderTank class should have a method that returns the volume of the tank. Next, you should create a WaterTank class that has a CylinderTank object as a field. It should also have a field for the cost of the labour per cubic metre. The WaterTank class should have a method called findTotalLabour Cost () that returns the total labour cost for building the tank. The following diagram shows possible class design and depicts the relationship between the WaterTank and Cylinder Tank classes. WaterTank -tankSize: CylinderTank -labourCost: double +WaterTank (tS: CylinderTank, cost: double) +findTotalLabour Cost (): double +toString(): String -radius: double -height: double CylinderTank +CylinderTank (rad: double, h: double) +getRadius (): double +getHeight (): double +getVolume (): double +toString(): String
