Ask the user to enter a number for red, green, and blue components of an RGB value, which takes a certain amount of red, green, and blue colors and produces a new color. Test the numbers that are input by the user and check that each value is between 0 and 255 (inclusive). If a color's value is outside of this range, print which color's number is not correct (e. g., "Red number is not correct" if the red value is 300). Multiple colors may be out of range. The order of the colors should be the same as the sample runs below; red, then green, then blue. Hint: Since this lesson uses boolean operators, remember to use at least one boolean operator in each of your answers to receive full credit.

Sample Run 1
Enter the red: 150
Enter the green: 300
Enter the blue: 15
Sample Output 1
Green number is not correct.
Sample Run 2
Enter the red: 25
Enter the green: 124
Enter the blue: 105
Sample Output 2
Nothing is output if a user enters three numbers that are all within the range of 0 to 255.

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."
