Answer:

C++ Program to Find Area and Circumference of a Circle

Area of Circle = PI X Radius X Radius. Where, Where PI is a constant which is equal to 22/7 or 3.141(approx)

Circumference or Circle = 2 X PI X Radius.

Circumference or Circle = PI X Diameter.

Answer:

/*********************************************************************************

* (The ComparableCircle class) Define a class named ComparableCircle that *

* extends Circle and implements Comparable. Draw the UML diagram and implement *

ComparableCircle comparableCircle1 = new ComparableCircle(12.5);

ComparableCircle comparableCircle2 = new ComparableCircle(18.3);

// Display comparableCircles

#include

gavmur [86]

Answer:

See explaination

Explanation:

#include <fstream>

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

// Fill in the code to define payfile as an input file

ifstream payfile;

float gross;

float net;

float hours;

float payRate;

float stateTax;

float fedTax;

cout << fixed << setprecision(2) << showpoint;

// Fill in the code to open payfile and attach it to the physical file

// named payroll.dat

payfile.open("payroll.dat");

// Fill in code to write a conditional statement to check if payfile

// does not exist.

if(!payfile)

{

cout << "Error opening file. \n";

cout << "It may not exist where indicated" << endl;

return 1;

}

ofstream outfile("pay.out");

cout << "Payrate Hours Gross Pay Net Pay"

<< endl << endl;

outfile << "Payrate Hours Gross Pay Net Pay"

<< endl << endl;

// Fill in code to prime the read for the payfile file.

payfile >> hours;

// Fill in code to write a loop condition to run while payfile has more

// data to process.

while(!payfile.eof())

{

payfile >> payRate >> stateTax >> fedTax;

gross = payRate * hours;

net = gross - (gross * stateTax) - (gross * fedTax);

cout << payRate << setw(15) << hours << setw(12) << gross

<< setw(12) << net << endl;

outfile << payRate << setw(15) << hours << setw(12) << gross

<< setw(12) << net << endl;

payfile >> hours ;// Fill in the code to finish this with the appropriate

// variable to be input

}

payfile.close();

outfile.close();

return 0;

}

Why do you think a business would set the price of their product above the competition

Flauer [41]

because a business wants you to buy their product. Its like gas prices, when one gas price is lower than another stores, people tend to go to the one with the lower price.

there are four stage of the product life cycle. during which of these stages do you think is the best time for a company to purc

Alisiya [41]

Maturity Stage – During the maturity stage, the product is established and the aim for the manufacturer is now to maintain the market share they have built up. This is probably the most competitive time for most products and businesses need to invest wisely in any marketing they undertake. They also need to consider any product modifications or improvements to the production process which might give them a competitive advantage. i think this would be the best time for the company to purchase an emerging technology.

What is the safety for working ina facility that performs xrays?

mylen [45]

Hey and thanks for giving me the chance to serve u

For the nuclear industry, the NRC, amongst other things, dictates exposure limits to both workers dealing with radioactive material, called the occupationally exposed, and the general public, or non-occupationally exposed. For an occupationally exposed worker, such as someone at a nuclear power plant or in nuclear medicine at a hospital (if they’re licensed by the NRC), the limit is 5 rem a year. Surprisingly, while most nuclear power workers never receive anywhere close to that amount, some workers in the medical field, such as those working with X-ray fluoroscopy machines, are amongst the highest occupationally exposed workers. Pregnant women who are occupationally exposed may choose to (but are not required to) declare their pregnancy and receive lower dose limits throughout the term of the pregnancy.

For members of the public, the annual limit from the NRC (which is matched by the EPA for areas not covered by NRC guidelines) is 100 mrem. Licensed facilities have to have programs in place to limit exposure, and be able to demonstrate that procedures are in place that members of the public would not be exceeding those levels.
