2.1 Area of a Pizza Pie Pizzas in the USA are just big circles of bread, cheese, and tomato sauce sured by the size of their diameter in inches. You can use that to get the area of the circle, which is measured in square inches. Write a method which takes in the diameter of a circle and returns the area. Remember: d = 2r 2.2 Computing the Price per Square Inch Figuring out the price per square inch should be its own method. Given the area of a circle in square inches and the price, the method should return the price per square inch. 2.3 Interactivity Your program should be interactive. This means that the program should ask the user to enter the size of the pizza and the price.4 All the input from console and output to the user5 should happen on in main. 3 Grading Criteria As this is half of this week's assignment, this one is worth 50 points.
