Consider the following program segment. Suppose choice is a variable with the data type char and num1, num2, and num3 are variables with int data types. Suppose further that before the execution of the program segment, the value of choice is ‘b’ and the values of num1, num2 and num3 are 5, 2 and -3 respectively. What is the value of num1 after the execution of the program segment?

please finish the function definition and dont use local variables please and thank you! for area_of_disk(radius): return math.pi * radius ** 2

C++ Program          Write a CPP program to do the following using recursion: 1. Using the current estimated population of 7.7 Billion and an estimated growth rate of 1.06%,  compute the estimated year when the population year could exceed over 20 Billion. 2. Display the year (2xxx) and estimated population values for each year as you do this processing. 3. Start with the current year and display the data in ascending order.  I am specifying this as it is possible to report this in descending order if the display is done after the recursion. For this assignment, create a method that calls itself recursively, passing the year and current population to itself.  You can increase the population by applying  * 1.0106  to increase by 1.06%. This method can return void and thus should do all the displays and computations needed. Display the year processed and estimated population value.. The variable for the population should be a double data type. Do not allow the display to be in scientific…
