Pizza Pi
Joe’s Pizza Palace needs a
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.
A) 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 = πr2
NOTE: π is the Greek letter pi. 3.14159 can be used as its value. The variable r is the radius of the pizza. Divide the diameter by 2 to get the radius.
Make sure the output of the program displays the number of slices in fixed-point notation, rounded to one decimal place of precision. Use a named constant for pi.

- Python code easy way pleasearrow_forwardParty-On sells individual hot/cold cups and dessert plates for parties. SueChen wants a program that allows her to enter the price of a cup, the price of a plate, the number of cups purchased, and the number of plates purchased. The program should then calculate the total cost of the purchase, including the sales tax. Finally, the program should display the total cost on the screen. Desk-check your solution’s algorithm using $0.50 as the cup price, $1 as the plate price, 35 as the number of cups, 35 as the number of plates, and 2% as the tax rate. Then desk-check it using $0.25, $0.75, 20, 10, and 6%.arrow_forwardJoe’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: 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
- Odd Even Number Problem Description Even Numbers are integers that are exactly divisible by 2, whereas an odd number cannot be exactly divided by 2. Example of even numbers are 2,4,6,8 and odd numbers are 1, 3, 5, 7, 9. Input The first line input contains an integer, which determines the number of test cases. Each of following lines represent sequence of integers that ends with 0. 2 34 1 8 5 22 0 10 7 16 -2 0 Output For each test case, the output will present the size of oddQueue and evenQueue following with the integers of odd and even numbers. oddQueue 2: 1 5 evenQueue 3: 34 8 22 oddQueue 1: 7 evenQueue 3: 10 16 -2 ** Your task is to write a program that will read the input and identify whether it is an odd number or even number. /******************************************************************************* Compilation: javac Queue.java** The Queue class represents a first-in-first-out (FIFO) queue of generic items.* It supports the usual enqueue and dequeue…arrow_forwardAn online book club awards points to its customers based on the number of books purchased each month. Points are awarded as follows: Books Purchased Points Earned 1 5 2 15 3 30 4 or more 60 Write a program that asks the user to enter the number of books purchased this month and then displays the number of points awarded.arrow_forwardHide Assignment Information Instructions The civil engineering department has asked you to write a program to compare three different designs of water towers shown in the diagrams below. The water towers are a cylinder topped with a half sphere. The engineers want to find the design that has the highest volume. The radius of the sphere and the radius and height of the cylinder for each of the three projects will need to be input by the user. The formula for the volume of a Sphere is:V = 4/3 π r3The formula for the volume of a Cylinder is:V = π r2 h Write two functions that will calculate the volume of a sphere and a cylinder respectively. Then, use these functions to write a program that will find the design with the largest volume. Hint: Remember that the tower only consists of a half sphere.arrow_forward
- flowchart 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_forwardWidgets and Gizmos An online retailer sells two products: widgets and gizmos. Each widget weighs 75 grams. Each gizmo weighs 112 grams. Write a program that reads the number of widgets and the number of gizmos in an order from the user. Then your program should compute and display the total weight of the order.arrow_forwardTime 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_forward
- 9. Shipping Charges The Fast Freight Shipping Company charges the following rates: Weight of Package 2 pounds or less Over 2 pounds but not more than 6 pounds Over 6 pounds but not more than 10 pounds Over 10 pounds Rate per Pound $1.10 $2.20 $3.70 $3.80 Design a program that asks the user to enter the weight of a package and then displays the shipping charges.arrow_forwardInterest 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_forwardQustion number 3 using paython, please!arrow_forward
