Using a switch statement and three functions, write a C++ 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 call a function circle that computes and displays the circle's area. Use the following formula calculate the circle area: Area = atr, where it has a value 3.14159 and ris the radius of the circle. If the user enters 2, the program should ask for the length and width of the rectangle and then calls a function rectangle that computes and displays the rectangle's area. Use the following formula to calculate the rectangle area, 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 call a function triangle that computes and displays the triangle's area. Use the following formula to calculate the area: area= base height *.5 If the user enters 4, the program should end. The program should also display an error message if the user enters a number outside the range of 1 through 4
