Write a C++ class named Cone that consists of TWO float attributes, radius and slantHeight, by answering the following questions: a) Implement the following constructors: An empty and parameter-less constructor. A constructor that accepts as parameters the radius and slantHeight attributes. (3 marks) b) Implement class functions that: Allows a user to enter the code dimensions. Calculate and return the volume of the cone [volume = "/3]. Calculate and return the surface area of the cone (surface area = nr(r +- (2 marks) c) Implement a "getter" and a "setter" for both attributes. (3 marks) (3 marks) h +r). (3 marks) Display all the information related to the cone namely the radius, slant height, volume, and surface area. (5 marks) (4 marks) d) Implement a main function that instantiates an instance of a Cone and then asks a user to input the required dimensions. The program should then display all the information related to the sphere on the screen by invoking the appropriate functions.
