please answer the following in C++

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. ( 2 marks) - 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. ( 3 marks) - Calculate and return the volume of the cone [volume =h/3r2 ]. ( 3 marks) - Calculate and return the surface area of the cone (surface area =r(r+h2+r2). (3 marks) - Display all the information related to the cone namely the radius, slant height, volume, and surface area. (5 marks) c) Implement a "getter" and a "setter" for both attributes. (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
