Project 3

The Projects

For the following, write a program that reads the necessary information to compute and output the indicated values, as efficiently as possible. Following the pattern in the lab exercise, first, design using OCD; then code your design in C++ using stepwise translation; finally, test your program thoroughly.

For each of these projects, PI should be declared as a constant:

const double PI = 3.14159;

Project #3.1: Write a program to find the circumference and area of a circle. The formulas for these quantities are as follows:

circumference = 2·π·radius
area = π·radius²

Project #3.2: Write a program to find the side surface area and volume of a regular cylinder. The formulas for these quantities are as follows:

sideSurfaceArea = 2·π·radius·height
volume = π·radius²·height

Project #3.3: Write a program to find the circumference and area of an ellipse. The formulas for these quantities are as follows:

circumference = 2·π·the square root of ( ( (height/2)² + (width/2)²) / 2 )
area = π·(height/2)·(width/2)

Project #3.4: Write a program to find the surface area and volume of any sphere. The formulas for these quantities are as follows:

surface area = 4·π·radius²
volume = (4/3)·π·radius³
