First of all, a bit of theory: since the area of a square is given by 

where s is the length of the square. So, if we invert this function we have
 .
.
Moreover, the diagonal of a square cuts the square in two isosceles right triangles, whose legs are the sides, so the diagonal is the hypothenuse and it can be found by

So, the diagonal is the side length, multiplied by the square root of 2. 
With that being said, your function could be something like this:
double diagonalFromArea(double area) {
 double side = Math.sqrt(area);
 double diagonal = side * Math.sqrt(2);
 return diagonal;
}
 
        
             
        
        
        
Answer:
   455 or 680, depending
Step-by-step explanation:
If we assume the three choices are different, then there are ...
   15C3 = 15·14·13/(3·2·1) = 35·13 = 455
ways to make the pizza. 
___
If two or three of the topping choices can be the same, then there are an additional ...
   2(15C2) +15C1 = 2·105 +15 = 225
ways to make the pizza, for a total of ...
   455 + 225 = 680
different types of pizza.
__
There is a factor of 2 attached to the number of choices of 2 toppings, because you can have double anchovies and tomato, or double tomato and anchovies, for example, when your choice of two toppings is anchovies and tomato.

Answer:
$ 24.30
Step-by-step explanation:
1. $32.40 multiplied by 15 which would equal 486
2. Then you would do 486 divided by 20 which would equal $24.3
3. Then you just add the zero the the end
