Universal containers uses a custom object within the product development team. product development, executives, and system administrators should be the only users with access to records of this object. product development needs read/write access to all the records within the object, while the executives should only be able to view the records.

how can the system administrator configure the security model to meet these requirements?

a. set the organization-wide defaults for the custom object to public read write; create a read only sharing rule to share all records in the object with the executive public group.
b. set the organization-wide defaults for the custom object to public read write; give the product development profile read, create, edit permissions; give the executive profile read only permissions for that object.
c. set the organization-wide defaults for the custom object to private; add the executive users to the default team for the object; add the default team to all the records.
d. set the organization-wide defaults for the custom object to private; give the product development profile modify all for the object; give the executive profile view all access.

Write a program that displays the following menu: geometry calculator 1. calculate the area of a circle 2. calculate the area of a rectangle 3. calculate the area of a triangle 4. quit enter your choice (1-4): if the user enters 1, the program should ask for the radius of the circle and then display its area. use the following formula: area = ď€(the square of r) use 3.14159 for ď€ and the radius of the circle for r. if the user enters 2, the program should ask for the length and width of the rectangle and then display the rectangle’s area. use the following formula: area = length * width if the user enters 3, the program should ask for the length of the triangle’s base and its height, and then display its area. use the following formula: area = base * height * .5 if the user enters 4, the program should end. input validation: display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu. do not accept negative values for the circle’s radius, the rectangle’s length or width, or the triangle’s base or height. note: if the user enters an improper menu choice (1-4), the program prints "the valid choices are 1 through 4. run the program again and select one of those." if the user enters a negative radius, the program prints "the radius can not be less than zero." if the user enters a negative value for height or base, the program prints "only enter positive values for base and height."
