(The conical paper cup problem) You have been given the contract for making little conical cups that come with bottled water.
These cups are to be made from a circular waxed paper of 4 inches in radius by removing a sector of length x (see Figure 5-4 below). By closing the remaining part of the circle, a conical cup is made.
Your objective is to remove the sector so that the cup is of maximum volume.
Instructions
Write a program that prompts the user to enter the radius of the circular waxed paper.
The program should then output:
The length of the removed sector so that the resulting cup is of maximum volume
The maximum volume
Calculate your answer to two decimal places.Use 3.141592654 for PI

Format your output with setprecision(2) to ensure the proper number of decimals for testing!
(Rounding Numbers) An application of function floor is rounding a value to the nearestinteger. The statementy = floor(x + .5);will round the number x to the nearest integer and assign the result to y. Write a program that readsseveral numbers and uses the preceding statement to round each of these numbers to the nearestinteger. For each number processed, print both the original number and the rounded number.

- (In java) Lab6C: Cha-Ching For this lab, use a do-while loop.A sentinel loop is a loop (a special while loop or a do-while loop) that continues to process data until itreaches a specific value(s) that signals that it should stop looping; this special value(s) is usuallyindicated as the condition of the while or do-while loop. A good example of a sentinel loop is the whileloop that you had to write to verify user input in Lab6B, the special values were anything in the range of1 to 1000. Another very common application for this is allowing a user to rerun a program.Please write a very simple program that mimics a bank account. The program should start the user outwith $1000. The program should print out a welcome menu once with the options present for the user.The program should allow the user to make a deposit, withdrawal, and see their current balance.Every time the user deposits or withdraws, the program should show the user their new balance; itshould also ask the user if they want…arrow_forward(Perfect Numbers) An integer number is said to be a perfect number if its factors, including1 (but not the number itself), sum to the number. For example, 6 is a perfect number because 6 =1 + 2 + 3. Write a function isPerfect that determines whether parameter number is a perfect number. Use this function in a program that determines and prints all the perfect numbers between 1and 1000. Print the factors of each perfect number to confirm that the number is indeed perfect.Challenge the power of your computer by testing numbers much larger than 1000.arrow_forward(Financial application: compute future tuition)Suppose that the tuition for a university is $10,000 this year and increases 5% every year. Write a program that computes the tuition in ten years and the total cost of 4 years’ worth of tuition starting after the 10th year.arrow_forward
- (Please make sure to match the screenshot below in output) Rolling a single six-sided die produces a random number between 1 and 6 with a uniform distribution. Rolling two dice produces a number between 2 and 12 with a binomial distribution. In this lab you will simulate a number of dice rolls and graph the number of occurrences of each value. 1) Create a function called rollDie() that takes no parameters, and returns a random value between 1 and 6. Do not seed the random number generator in this function. int rollDie() 2) Create a function called initArray() that takes a data array and the size of the array as parameters and fills each element with the summed results of rolling two dice. Do not assume that the data array has been initialized. void initArray(int data[], int size) 3) Create a function called sortArray() that takes an array and the size of the array as parameters, and sorts the array using the sediment sort. void sortArray(int data[], int size) The sediment sort works…arrow_forward[THIS IS NOT GRADED] The question mentions the bouncy program; this is the bouncy program I have written that computes the total distance traveled by the ball given initial height, bounciness index, and number of bounces: height = float(input("Enter the height from which the ball is dropped: ")) bounciness = float(input("Enter the bounciness index of the ball: ")) distance = 0 bounces = int(input("Enter the number of times the ball is allowed to continue bouncing: ")) for eachPass in range(bounces): distance += height height *= bounciness distance += height print('\nTotal distance traveled is:', distance, 'units.') I will attatch the pre-existing code that the question provided. Thank you for your help.arrow_forward(Rounding Numbers) Function floor can be used to round a number to a specific decimal place. The statementy = floor(x * 10 + 0.5) / 10;rounds x to the tenths position (the first position to the right of the decimal point). The statementy = floor(x * 100 + 0.5) / 100;rounds x to the hundredths position (the second position to the right of the decimal point). Write a program that defines fourfunctions to round a number x in various ways:A. roundToInteger(number)B. roundToTenths(number)C. roundToHundredths(number)D. roundToThousandths(number)For each value read, your program should print the original value, the number rounded to the nearest integer, the number rounded to the nearest tenth, the number rounded to the nearest hundredth and the number rounded to the nearest thousandth.arrow_forward
- (Python matplotlib or seaborn) CPU Usage We have the hourly average CPU usage for a worker's computer over the course of a week. Each row of data represents a day of the week starting with Monday. Each column of data is an hour in the day starting with 0 being midnight. Create a chart that shows the CPU usage over the week. You should be able to answer the following questions using the chart: When does the worker typically take lunch? Did the worker do work on the weekend?
