We are given square with side length l. The largest circle that we can cut from that square has diameter equal to that side. This circle is called inscribed circle.
When cutting circle from square paper we will be left with some extra paper. Area of that extra paper can be calculated using formula:
area_of_extra_paper = area_of_square - area_of_circle
Now we can insert formulas:
This is area of extra paper when we cut one circle. When we cut multiple circles we have:
Where:
N = number of circles
This formula is roughly:

Answer: The tan 130° is expressed as
Step-by-step explanation:
Since we have given that
As we know that
cos (π - θ ) = -cos θ
so, cos(180-50)=-cos 130° = -a
so, sin 130° would become
So, tan 130° is given by
Hence, the tan 130° is expressed as
