programing in C#

Write a program to compute the diameter in centimeters of a steel rod, an aluminum rod, a copper rod, which can withstand a particular compression load.  The allowable compression stress of steel, aluminum, and copper is 25,000lbs/m (square), 15000lbs/m (square), and 20,000lbs/m (square), respectively. 

                                Area of rod = compression load

                                                          Allowable compression stress

                                 Where diameter d = 2r

Input the compression load.  Print the type of material, load, allowable stress, and diameter.  Use formatted output with field width specifications that align the output.
