82 - 7 = 75
Answer:


Step-by-step explanation:







Given :
Diameter of pizza ,
.
To Find :
Is square box of size equal to diameter big enough to fit pizza inside it .
Solution :
Area of pizza :

Area of square with side equal to diameter :

Since , the area of square is more than area of pizza .
Therefore , pizza can easily be fitted .
Hence , this is the required solution .
See attached scatter plot
this does not show a linear pattern
Remember that transformation between Cartesian and polar system are:
x=r*cos(α)
y=r*sin(α)
From this we can conclude that:
r=√(x^2 + y^2)
Using trigonometry transformations we can write:
r=sin(2α) = 2sin(α)cos(α)
Now we can multiply both sides with r^2:
r^3 = 2(r*sin(α))*(r*cos(α))
Now using some replacements we can write:
(x^2 + y^2)^(3/2) = 2*x*y
