How many discs of one-inch diameter can you fit in a rectangle of size 5 inches by 3.6 inches? (In a sense, the capacity of the rectangle with respect to the discs)
(This is a two-dimensional problem - you cannot stack discs)
Homework Answers
Total = 5+4+5+4 = 18
Arrangement will be like:
Area of disc = pi*((d/2)^2 = 3.14*(0.5)^2 = 0.785
Area of rectangle = l*b = 5*3.6 = 18
Maximum Number of disc possible = Area of rectangle/Area of disc = 18/0.785 = 22.9
So, 18 is possible basis hit and trial

Create a C++ to calculate how many circles can fit in a square. Ask the user for the side of the square and the diameter of the circle. Tell the user how many of those circles can fit in the square. They do not have to be full circles. For instance, the answer can be 2.79. Use 3.14159265358979 for the value of PI and PI must be a constant Format your output to display two decimals.

Set 5 a. A staircase has 10 steps. You walk up taking one or two at a time. How many ways can you go up? We have n dollars to spend. Every day we either buy a candy for 1 dollar, or an ice cream for 2 dollars. In how many ways can we spend the money? Explain for n-5, and then conjecture for n dollars. Prove your conjecture. Define Fibonacci numbers completely. Why do you need two initial values?...
