Geometry Calculator

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 (l-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 to calculate the circle's area:

area= 'TTr2

Use 3.14159 for 'TT 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 to calculate the rectangle's area:

area = length X 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 to calculate the area of the triangle:

area = base X height X .5

If the user enters 4, the program should end.

Explanation / Answer

#include #include using namespace std; int displayMenu(); double calcAreaCircle( double radius ); double calcAreaRect( double length, double width ); double calcAreaTriangle( double base, double height ); const double Pi = 3.14159; int main () { double menu; menu=displayMenu(); double circ_area; circ_area = calcAreaCircle (); double rect_area rect_area = calcAreaRect (); double tri_area tri_area = calcAreaTriangle (); switch(choice) { case 1: { cout
