Area table

Problem:



Solution:

The radius is half the square side length $r = \frac{x}{2}$
The square plot area is square of the side length $A_{square} = x \times x$
The flower area is $A_{flower} \pi \times r \times r$
The grass area is $A_{grass} = A_{square} - A_{flower}$.

The numbers are computed as follow:

Square side	Radius	Square Area	Flower Area	Grass Area
1.00	0.50	1.00	0.79	0.21
2.00	1.00	4.00	3.14	0.86
3.50	1.75	12.25	9.62	2.63
6.00	3.00	36.00	28.27	7.73
