Mass and Weight
Scientists measure an object’s mass in kilograms and its weight in Newtons. If you know the amount of mass that an object has, you can calculate its weight, in Newtons, with the following formula:

- Joe’s Pizza Palace needs a program to calculate the number of slices a pizza of any size can be divided into. The program should perform the following steps: Ask the user for the diameter of the pizza in inches. Calculate the number of slices that may be taken from a pizza of that size. Display a message telling the number of slices. To calculate the number of slices that may be taken from the pizza, you must know the following facts: Each slice should have an area of 14.125 inches. To calculate the number of slices, simply divide the area of the pizza by 14.125. The area of the pizza is calculated with this formula: Area = "pi r squared" where pi is approximately 3.14159 and r is the radius (half the the diameter). coding should be in c++arrow_forwardA car’s miles-per-gallon (MPG) can be calculated with the following formula:MPG 5 Miles driven Gallons of gas usedWrite a program that asks the user for the number of miles driven and the gallons of gas used. It should calculate the car’s MPG and display the result.arrow_forwardAnswer this question Write a program that calculates and displays a person’s body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person’s BMI is calculated with the following formula:BMI = weight × 703 / height2where weight is measured in pounds and height is measured in inches. The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight. A sedentary person’s weight is considered to be optimal if his or her BMI is between 18.5 and 25. If the BMI is less than 18.5, the person is considered to be underweight. If the BMI value is greater than 25, the person is considered to be overweightarrow_forward
- Time CalculatorWrite a program that asks the user to enter a number of seconds.-There are 60 seconds in a minute. If the number of seconds entered by the user is greater than or equal to 60, the program should display the number of minutes and leftover seconds in that many seconds.-There are 3,600 seconds in an hour. If the number of seconds entered by the user is greater than or equal to 3,600, the program should display the number of hours, minutes, and leftover seconds in that many seconds.-There are 86,400 seconds in a day. If the number of seconds entered by the user is greater than or equal to 86,400, the program should display the number of days, hours, minutes, and leftover seconds in that many seconds.arrow_forwardQ#3: Develop a program to ask the user to enter a number, if the user enters a positive integer, then compute the factorial of that number and display it on the screen.arrow_forwardQustion number 3 using paython, please!arrow_forward
- Q: 3: Input a number/value from the user check whether it is negative or positive. If it is negative then convert it into a positive number.arrow_forwardBox Office: A movie theater only keeps a percentage (20%) of the revenue earned from ticket sales. The remainder goes to the movie distributor. Write a program that calculates a theater’s gross and net box office profit for a night. The program should ask for the name of the movie, and how many adult and child tickets were sold. (The price of an adult ticket is $10.00 and a child’s ticket is $6.00.) Input: the name of the movie, number of adult tickets sold, number of child tickets sold Output: as specified below Object: cin, cout, getline, format output Note: 1. Movie names contain spaces 2, the report is aligned. 3. The decimal number is displayed with 2 decimal places.arrow_forwardRetail price calculator Write a program that asks the user to enter an item’s wholesale cost and its markup percentage. It should then display the item’s retail price. For example: • If an item’s wholesale cost is 5.00 and its markup percentage is 100 percent, then the item’s retail price is 10.00.• If an item’s wholesale cost is 5.00 and its markup percentage is 50 percent, then the item’s retail price is 7.50. The program should have a method named calculateRetail that receives the wholesale cost and the markup percentage as arguments and returns the retail price of the item.arrow_forward

The program should perform the following steps: A) Ask the user for the diameter of the pizza in inches.B) Calculate the number of slices that may be taken from a pizza of that size if each slice has an area of 14.125 square inches.C) Display a message telling the number of slices.The number of square inches in the total pizza can be calculated with this formula:Area = πr2where variable r is the radius of the pizza and π is the Greek letter PI. In your program make PI a named constant with the value 3.14. Display the number of slices as a whole number (i.e., with no decimals).arrow_forward
