2. Write the algorithm and write the C++ code that calculates and prints the volume of the water in a cone shape tank, as shown in Figure 2. The radius of the cone base is known = 4 meters. The height of the water level can be given by the user and the radius of the top water level is given by the user. Notice: the volume of the water in the tank can be calculated by the following equation: The value of is = 3.14159. Figure 2: Cone Shape Water Tank
