(Geometry: area of a regular polygon) A regular polygon is an n-sided polygon inwhich all sides are of the same length and all angles have the same degree (i.e., thepolygon is both equilateral and equiangular). The formula for computing the areaof a regular polygon isn x s?Area4 X tanHere, s is the length of a side. Write a program that prompts the user to enter thenumber of sides and their length of a regular polygon and displays its area. Here isa sample run:

import java.util.Scanner; public class AreaOfAregularPolygon4_5 { public static void main…

(Sort three integers) Write a program that prompts the user to enter THREE integers and display the integers in decreasing order. Prepare your problem analysis and algorithm (pseudocode or flowchart) to plan your solution.
[Using program 'Flowgorithm']: A gallon of paint covers 422 square feet and costs $29.85. Using flowgorithmdetermine and display the amount of paint it will take to paint a fence of aspecified height and length, the fence is solid not rails. Your program shouldperform the following tasks: Declare all required variables Declare constants and initialize them Prompt for the input of the fence height Prompt for the input of the fence length Calculate the total square feet to be painted Calculate the required number of gallons of paint required withoutusing a partial gallon of paint Display the total square feet to be painted,the number of gallons of paint needed and the total cost of the paint Ask if a second estimate needs to be made (keep program running until toldto stop)I have the basic steps complete, but am struggling to create a program which continues to run until told to stop. Suggestions on loop elements are hugely appreciated!

4. (Check SSN) Write a program that prompts the user to enter a Social Security number in the format DDD-DD-DDDD, where D is a digit. Your program should check whether the input is valid. Here are sample runs: Enter a SSN: 232-23-5435 JEnter 232-23-5435 is a valid social security number Enter a SSN: 23-23-5435 JEnter 23-23-5435 is an invalid social security number
(Slope of a line) Write a program that prompts the user to enter the coordinates of two points (x1, y1) and (x2, y2), and displays the slope of the line that connects the two points. The formula of the slope is (y2 - y1)/(x2 - x1).
(Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1+2+3+4 = 10 and 1 +0 = 1, while 1235 is not (1 +2+ 3 +5 = 11 and 1 +1 = 2). Write a program that prints out the first N magic numbers, seven on each line. Here is the sample output: Enter a positive integer number: 30 1 10 19 28 37 46 55 64 73 82 91 100 109 118 127 136 145 154 163 172 181 190 199 208 217 226 235 244 253 262 You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of value Step 2: Repeat Step 1 until we get a single digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise not
