in phython language Create a package folder named shapes. Inside this package, place two more package folders: 2d and 3d. Inside 2d package, place a module file: circle.py circle.py module has two function definitions: areaCircle(), circCircle(). areaCircle() function takes a parameter: radius, calculates and returns the area of the circle. You may assume PI is 3.14. circCircle() function also takes a parameter: radius, calculates and returns the circumference of the circle. Inside 3d package, place two module files: sphere.py and cylindir.py sphere.py module has two function definitions: areaSphere() and volumeSphere() which both take a parameter for radius, calculates and returns area and volume of a sphere respectively. cylindir.py module has two function definitions: areaCylindir() and volumeCylindir() which both take two parameters: height and radius. They calculate area and volume of a cylindir and return the values respectively. You may find the formulas for those shapes…

Please written by computer source Unit 4 - Lab – Individual Retirement Account Calculation Assignment An Individual Retirement Account (IRA) is a special bank / brokerage account that a person can use to save money for retirement. An individual can put up to $5,500 per year tax free and the money grows tax free until the person is ready to retire. The tax rules related to IRA’s are complex, but for this assignment, we’ll assume that the person puts in the same amount of money every year (up to $5,500) and the money grows at a constant interest rate. Write a Flowgorithm program that asks the user to input an annual IRA contribution (in dollars), and interest rate (percent), and a time period (years). Calculate the value of the IRA every year for the duration of the time period provided by the user. Be sure and provide user friendly prompts. Include a comment at the beginning of the program with your name, date, and a short description of the program.

Instructions: In the code editor, you are provided with the definition of a struct Person. This struct needs an integer value for its age and a character value for its gender. Furthermore, you are provided with a displayPerson() function which accepts a struct Person as its parameter. In the main(), there are two Persons already created: one Male Person and one Female Person. Your task is to first ask the user for the age of the Male Person and the age of the Female Person. Then, define and declare a function called createKidPerson() which has the following definition: Return type - Person Name - createKidPerson Parameters Person father - the father of the kid to be created Person mother - the mother of the kid to be created Description - creates a new Person and returns this. The age of this Person will be set to 1 while its gender will be set based on the rules mentioned above. Finally, create a new Person and call this createKidPerson() in the main and then pass this newly…
