A. Input, Output and Processing Results Write a C++ program called Lab3A.cpp that reads input from the keyboard and prints output to the screen using cin and cout, respectively. Specifically, you are to write a C++ program that does the following to calculate the surface area of a cylinder as follows r radius h height Assign the value 3.14 to a variable called pi. Prompt for and read in the radius of the cylinder. Prompt for and read in the vertical height of the cylinder. . Calculate the area of the trapezoid using the formula Area 22+h(2) where r is the radius, h is the height, and is pi. Be sure to use the pow() function to calculate the radius squared. Print the area result of the cylinder in a meaningful message to the terminal
