Use Archimedes’ principle to develop a steady-state
force balance for a spherical ball of ice floating in seawater.
The force balance should be expressed as a third-order poly-
nomial (cubic) in terms of height of the cap above the water
line (h), and the seawater’s density (ρf
), the ball’s density
(ρs) and radius (r).

Write a C++ program to first allow a user to input n integer numbers into array X and then sort the contents of the array descending order and finally print on the screen both the sorted and the unsorted arrays.
Ask the user to enter the values for sides A, B, C, D, and E and print out the total room area.

Remember the formula for finding the area of a rectangle is length * width and the area of a right triangle is 0.5 * the base * height.

Please note the final area should be in decimal format.
Use the methods find() and pretty() to implement the following queries.

(9) Display in a pretty format the names of drivers who performed no trips so far.
(10) Display in a pretty format names of drivers who started at least on trip in
Wollongong.

A builder needs a app developed that will support them in pricing up a job. The parameters that affect the job are:
The hourly rate (£20 per hour)
Distance to job (£3 per mile)
Overall material cost
If the job is less than 10 hours add an additional £50, for example, a 9 hour job would be (9X20) + 50
You will need to show the job with and without VAT (additional 20% of total job cost)
Don’t forget data validation

Assume the user types in 7 and 10.What is the output?
