9. Geometry Calculator Design a Geometry class with the following methods: . A static method that accepts the radius of a circle and returns the area of the circle Use the following formula: Area = 2 Use Math.PI for and the radius of the circle for r. . A static method that accepts the length and width of a rectangle and returns the area of the rectangle. Use the following formula: Area = Length Width . A static method that accepts the length of a triangle's base and the triangle's height. The method should return the area of the triangle. Use the following formula: Area-base Height 0.5 The methods should display an error message if negative values are used for the circle's radius, the rectangle's length or width, or the triangle's base or height. Next, write a program to test the class, which displays the following menu and responds to the user's selection: 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): Display an error message if the user enters a number outside the range of 1 through 4 when selecting an item from the menu
