Each tuple has two floating point values that are both greater than zero. The first value is the radius r and the second value is the height h. The volume of the cylinder is computed using ??2h. The value π is represented in F# with System.Math.PI. If the list is empty, return 0.0.

Insert the numbers in the queue till the queue reaches the size. Create a menu and perform the following function on that queue. This is all done by using oop in C++. Enqueue: Add an element to the end of the queue Dequeue: Remove an element from the front of the queue IsEmpty: Check if the queue is empty IsFull: Check if the queue is full Peek: Get the value of the front of the queue without removing it
- Code in python Given a list, L, the function front_two creates a new list of length 2 out of the first two items in L as follows: In the new list, the second item becomes the first item, and the first item becomes the second. If L contains only one item, the first item in the new list should be the value None. If L is empty, both items in the new list should be value None. The function returns the new list. For example: Test Result L = ['a', 'b', 'c', 'd'] print(front_two(L)) ['b', 'a'] L = [] print(front_two(L)) [None, None] L = [5, 2] print(front_two(L)) [2, 5] L = [7] print(front_two(L)) [None, 7]Write a program in Java, Python and Lisp When the program first launches, there is a menu which allows the user to select one of the following five options: 1.) Add a guest 2.) Add a room 3.) Add a booking 4.) View bookings 5.) Quit The functionality of these options is as follows: 1.) When users add a guest they provide a name which is stored in some manner of array or list. Guests are assigned a unique ID value where the first guest added is assigned the ID value 1, the second guest added is assigned the ID value 2 and so on. 2.) When users add a room they provide a room number and a room capacity (i.e. how many people can stay in the room at any one time) which is stored in some manner of array or list. Rooms have a property which indicates if they are booked or not for any given date – please see the Room Booking Dates section below for some guidance on the easiest way to implement this. 3.) When users add a booking they provide a guest ID, room number, the number…PYTHON CS1 PROBLEM Define a function that takes a list of lists, glol, as a parameter. You may assume that the inner lists in glol are lists of positive integers. Your function should return True if at least one of the inner lists in glol contains two or more multiples of 10. Otherwise it should return False. For example: If glol = [ ] then your function returns False. If glol = [[ ], [4, 2]] then your function returns False. If glol = [[10, 2, 6, 8], [12, 6], [15, 20, 5]] then your function returns False. If glol = [[10, 2, 6], [12, 6], [10, 2, 70, 15], [15, 10, 5]] then your function returns True as the inner list [10, 2, 70, 15] contains 10 and 70. If glol = [[10, 2, 6], [12, 6], [10, 7, 15], [50, 10, 50, 4, 6]] then your function returns True as the inner list [50, 10, 50, 4, 6] contains 50 twice. 6. If glol = [[10, 20, 6, 90], [12, 6], [ 7, 3, 15], [50, 10, 50, 4, 7]] then your function returns True as the inner lists [50, 10, 50, 4, 7] and [10, 20, 6, 90] contain more…
