2. Area of a Circle
Computer programs are great at computing mathematical formulas. Once the formula is properly encoded you can use the code as much as you want without reprogramming it and you can share it with non-
programmers without any trouble. This lab is an examply of such a formula. Once you program it you won't have to worry about the area of a circle again.
• Write and test a program that computes the area of a circle. This program should request a number representing a radius as input from the user.
• Use the formula 3.14 x radius? to compute the area.
• Tip: There are a couple of ways to code an exponent. Look in the Operators unit for help (and you can't use an x for multiplication).
• Tip: You will need to use the float data type to compute the remainder.
• The output should explain the results. Don't just print a number.
• Tip: For your print statement you will need to use the comma, or plus, *+" symbols to stitch your output together.
• (The area is, cyour variable>, "square units")
• Name the source code file yourName Lab3_2.py.
• Test and run the program. When testing use small numbers that you can easily test yourself to verify the program results. Capture the output console and save it as an image file named
yourName_LAB3_output2.jpg.
• Submit the py and the image files through Canvas.
NOTE: Below is sample output:
Lab 3 Part 2 Area of a Circle
Enter the radius of a circle: 5
The area of a circle with radius 5 is 78.5 square units.

They are just starting to learn about sine, cosine, and tangent. You've decided that you want to show the students what these functions look like when they have been graphed. Write a Python program to display three separate graphs for sin, cos, and tan. Add the ability to show all three graphs on a single graph with one row and three columns.arrow_forwardJava: Write a pseudocode algorithm that gets student exam scores from the user. Each exam score will be an integer in the range 0 to 100. Input will end when the user enters -1 as the input value. After all scores have been read, display the number of students who took the exam, the minimum score, the maximum score, the average score, and the number of As where an A is a score in the range 90-100. Make sure your average a decimal point. Only count A’s, not other grades. Note that you do not need to do any error checking on the input for this problem. This should be done as a standard sentinel-controlled while loop.arrow_forward
- JAVA LANGUAGE PLS THANK YOU 1. Squares by CodeChum Admin Looping random numbers and manipulating those values are fun, too! Why don't we try one that returns the square of an inputted number repeatedly until the user inputs 0? Let's do this! Instructions: Using a do...while() loop, continuously scan for random integers that will be inputted by the user and print out its square, separated in each line. Once the inputted value is 0, it will still print out its square value but should then terminate the loop afterwards. Use this concept in making your loop condition.

Your first task is to write an algorithm that recommends apartments based on a user’s preferences. Zillow offers the following three properties for rent: Apartment A – 600 square feet, pets allowed, 1400ドル/month Apartment B – 800 square feet, no pets, 1600ドル/month Apartment C – 1000 square feet, pets allowed, 1800ドル/month Write an algorithm for a program that does the following: Prompt the user for the minimum square footage they will accept, how many pets they have, and the maximum price they’d pay per month, and then calculate and output the apartments that match their preferences. If there is no apartment that matches their preferences, print out "No matches, sorry!". Make sure the inputs are valid--negative square footages, prices, and pet numbers don’t make sense!arrow_forwardDesign a Python program that tests your ESP, or extrasensory perception. The program will randomly pick a color, and you will be asked to predict the program’s selection before it is revealed. Design the program to randomly select one of the following words:Red, Green, Blue, Orange, YellowTo select a word, the program can generate a random number. For example, if the number is 0, the selected word is Red, if the number is 1, the selected word is Green, and so forth.Next, the program should ask the user to enter the color that the computer has selected. After the user has entered his or her guess, the program should display the name of the randomly selected color. The program should repeat this 10 times and then display the number of times the user correctly guessed the selected color.arrow_forward
- Python Algorithms Part 1 – Binary SearchLet's play a little game to give you an idea of how different algorithms for the same problem can have wildly different efficiencies. If I choose an integer from 1 to 16 and ask you to guess what the number is, you can keep guessing numbers until you hit on it. When you guess wrong, I tell you whether you are too high or too low. Once you've guessed the number, think about the technique you used to decide each of your next guesses.If you guessed 1, then 2, then 3, then 4, and so on, until you guessed the right number, you used an approach called "linear search," meaning you guessed the numbers serially and sequentially, as if they were lined up in a row. This is definitely one way to find the mystery number, but it could require as many as 16 guesses. However, you could get lucky, if the number was 1, you’d only need 1 guess. Using a linear search process, on average, you'd need 8 guesses.There is an approach that is more efficient than just...arrow_forwardThe following problem shows up in a number of Java texts, including Savitch's textbook: The Harris-Benedict equation estimates the number of calories your body needs to maintain your weight if you do no exercise. This is called your basal metabolic rate, or BMR. The calories needed for a woman to maintain her weight is: WBMR = 655 + (4.3 ×ばつ weight in pounds) + (4.7 ×ばつ height in inches) − (×ばつ age in years) The calories needed for a man to maintain his weight is: MBMR = 66 + (6.3 ×ばつ weight in pounds) + (12.9 ×ばつ height in inches) − (6.8 ×ばつ age in years) A typical chocolate bar will contain around 230 calories. Write a program that allows the user to input his or her weight in pounds, height in inches, and age in years. The program should then output the number of chocolate bars that should be consumed to maintain one’s weight for both a woman and a man of the input weight, height, and age.
