For this simulation, you will need a scoop class, a carton class and an icecreamshoppe class in addition to your application class (these classes described in the below uml diagrams). your ice cream shoppe should create two scoops with radii entered by the user, create a carton with radius and height entered by the user. then, you should ask the user if they would like ice cream. if they would, you should ask how many of the each size scoop and subtract the appropriate amount from the carton. if the requested amount ever exceeds the amount remaining in the carton, you should open a new carton to complete the order. continue asking the user until they indicate they are done. at the end, you should print how many cartons were used. remember that the volume of a sphere is (4/3)πr 3 and the volume of a cylinder is πr 2h. you can use math. pi where you want the value of π.

Formatting rows and columns is similar to cell formatting. in an openoffice calc spreadsheet, you can format data entered into rows and columns with the of the rows and columns options. you can insert rows and columns into, or delete rows and columns from, a spreadsheet. use the insert or delete rows and columns option on the insert tab. alternatively, select the row or column where you want new rows or columns to appear, right-click, and select insert only row or only column options. you can hide or show rows and columns in a spreadsheet. use the hide or show option on the format tab. for example, to hide a row, first select the row, then choose the insert tab, then select the row option, and then select hide. alternatively, you can select the row or columns, right-click, and select the hide or show option. you can adjust the height of rows and width of columns. select row and then select the height option on the format tab. similarly, select column, then select the width option on the format tab. alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. you can also use the autofit option on the table tab to resize rows and columns.
