Question

Write a program in C++ that solves this problem

Calculate the area and volume of a sphere problem.

Inside a for loop,

vary the radius from 10 to 40  with a step or increment of 5

and calculate the area and volume

Your radius will be equal to your loop counter.

All calculations should have 2 decimal places, but the radius should have zero decimal places and any number of 1,000 or more should have a comma.

Print the radius, area, and volume in a table format, with 3 columns. Note: you don’t have to print grid lines.

Print column headings above the loop and all the calculations inside the loop. The column headings would just be Radius, Area, and Volume. Right justify your data under your column headings

Below the loop, print the sum of the radii, the sum of the areas, and the sum of the volumes. The sum of the areas and the sum of the volumes should have 2 decimal places and commas. The sum of the radii should have zero decimal places.

Answer must be formatted like the following

Radius............Area...............Volume.

10            1,256.64            4,188.79

15            2,827.43           14,137.15

20            5,026.54           33,510.29

25            7,853.97           65,449.79

30           11,309.72          113,097.24

35           15,393.79          179,594.23

40           20,106.18          268,082.35

Totals:

Radius............Area...............Volume..

175           63,774.28          678,059.84

Radius             Area           Volume

       10      1,256.64          4,188.79

       15      2,827.43        14,137.17

       20      5,026.55        33,510.32

       25      7,853.98        65,449.85

       30    11,309.73      113,097.34

       35    15,393.80      179,594.38

       40    20,106.19      268,082.57

Sum of Radii:   175

Sum of Areas:   63,774.33

Sum of Volumes: 678,060.41
