I want the code using namespace std and use cout and cin

The surface area and volume of a sphere are given by following formulas, where R is the Sphere's radius, and r is a constant, area = 411R2 4 volume = AR3 As a programmer, your job is to write a complete Object-Oriented Program to solve for the surface area and volume of the Sphere. First, declare the class name as Sphere. The data members of the program are private. The surface area and volume should be the member function of the created class. The class also should have a mutator, accessor, and default constructor. The input is from the user, where you should ask for five(5) inputs of the radius. Use an array as the object. Then your program should be able to display the results to the screen and write them in a file name "sphere.txt". The sample output is as follows, Please input the radius of 5 different sphere in [m] 12.1 29.04 5.145 30 9.48 The results are as follows:- Radius[m] Surface Area[m2] Volume [3] [ 12.10 1839.84 5565.52 29.04 18597.49 76937.80 5.14 332.64 427.86 30.00 11309.73 84823.00 9.48 1129.34 2676.55
