Answer to Question #253041 in Algorithms for Israel

Question

create a flowchart that will Write an application that computes the area of a circle, rectangle, and cylinder. Display a menu showing the three options. Allow users to input which figure they want to see calculated. Based on the value inputted, prompt for appropriate dimensions and perform the calculations and perform the calculations using the following formulas:

Area of a circle = pi*radius2

Area of a rectangle = length*width

Area of a cylinder = pi*radius2*height

Write a modularized solution, which includes class methods for inputting data and performing calculations.
