Assuming that the user inputs a value of 25 for the price and a value of 10 for the discount rate in the following code snippet, what is the output? import java. util. scanner; public class determineprice { public static void main(string[] args){ scanner in = new scanner(system. in); system. out. print("enter the price: "); double price = in. nextdouble(); system. out. print("enter the discount rate: "); double discount = in. nextdouble(); system. out. println("the new price is " + (price - price * (discount / 100.; } }

Avariable definition defines the name of a variable that will be used in a program, as well as

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."
