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).

- Interest Rates Savings accounts state an interest rate and a compounding period. If theamount deposited is P, the stated interest rate is r, and interest is compounded m timesper year, then the balance in the account after one year is P⋅(1+rm)m. For instance, if$1000 is deposited at 3% interest compounded quarterly (that is, 4 times per year), thenthe balance after one year is1000⋅(1+.034)4=1000⋅1.00754=$1,030.34.Interest rates with different compounding periods cannot be compared directly.The concept of APY (annual percentage yield) must be used to make the comparison. TheAPY for a stated interest rate r compounded m times per year is defined byAPY=(1+rm)m−1.(The APY is the simple interest rate that yields the same amount of interest after oneyear as the compounded annual rate of interest.) Write a program to compare interestrates offered by two different banks and determine the most favorable interest rate. SeeFig. 4.24.arrow_forwardflowchart and pseudocode in problem solving and logic A painting company has determined that for every 150 square feet of wall space, one gallon of paint and nine hours of labor will be required. The company charges $25.00 per hour for labor. If the size of the wall is more than 1500 square feet company will charge only $ 23.00 per hour of labor. Design a modular program that asks the user to enter the square feet of wall space to be painted and the price of the paint per gallon. Pass those parameters to the Module and perform all the calculations inside that module. Avoid using ref variables. Provide a unique name for the module Your program should display the following data: The number of gallons of paint required The hours of labor required The cost of the paint The labor charges The total cost of the paint jobarrow_forwardFat Percentage Calculator One gram of fat has 9 calories. If you know the number of fat grams in a particular food, you can use the following formula to calculate the number of calories that come from fat in that food: Calories from fat = Fat grams × 9 If you know the food’s total calories, you can use the following formula to calculate the percentage of calories from fat: Percentage of calories from fat = Calories from fat ÷ Total calories Create an application that allows the user to enter: • The total number of calories for a food item • The number of fat grams in that food item The application should calculate and display: • The number of calories from fat • The percentage of calories that come from fat Also, the application’s form should have a CheckBox that the user can check if he or she wants to know whether the food is considered low fat. (If the calories from fat are less than 30% of the total calories of the food, the food is considered low fat.) Use the following test data…arrow_forward
