Assignment 2 – B. Distance between two points
The distance between two points (x1, y1) and (x2, y2) on a Cartesian coordinate plane is given by the equation
D=sqrt((x1–x2)2 +(y1–y2)2)
Write a program to calculate the distance between any two points (x1, y1) and (x2, y2) specified by the user. Use good programming practices in your program. Use the program to calculate the distance between (2, 3) and (8, -5).
Assignment 2 – C. Circle
Write a program that prompts the user for a radius r, and then prints
- The area and circumference of a circle with that radius.
- The volume and surface area of a sphere with that radius.
Test the results of your program for a circle and sphere with a radius of 7.5.
Assignment 2 – D. Change Calculator
Write a program that directs a cashier how to give change. The program has two inputs: the amount due and the amount received from the customer. Display the dollars, quarters, dimes, nickels, and pennies that the customer should receive. Note: This can be solved by using the %, and // operators sequentially.
In the following example, if Amount due = $ 6.13 Amount paid = $ 10.00 The program should print the following:
Change due = $ 3.73 Number of dollars = 3 Number of quarters = 2 Number of dimes = 2 Number of nickels = 0 Number of pennies = 3
