Answer:
Step-by-step explanation:
Bleeding Kansas, Bloody Kansas or the Border War was a series of violent civil confrontations in the United States between 1854 and 1861 which emerged from a political and ideological debate over the legality of slavery in the proposed state of Kansas. The conflict was characterized by years of electoral fraud, raids, assaults, and retributive murders carried out in Kansas and neighboring Missouri by pro-slavery "Border Ruffians" and anti-slavery "Free-Staters".
Hello :
the area is : A=<span>πr²
</span> π ≃ 3.14 r : <span>ridus
</span> <span>diameter = 2 r
</span>r = 18/2= 9 ft
A=3.14×9² = 254.34 ft²
This graph should help find the coordinates you need that was made of this inequality!
Instead of adding or subtracting 2pi (that's for radians only), just add or subtract 360 degrees to your angle.

The are 40320 ways in which the 5 indistinguishable rooks be can be placed on an 8-by-8 chess- board so that no rook can attack another and neither the first row nor the first column is empty
<h3 /><h3>What involves the
rook polynomial? </h3>
The rook polynomial as a generalization of the rooks problem
Indeed, its result is that 8 non-attacking rooks can be arranged on an 8 × 8 chessboard in r8.
Hence, 8! = 40320 ways.
Therefore, there are 40320 ways in which the 5 indistinguishable rooks be can be placed on an 8-by-8 chess- board so that no rook can attack another and neither the first row nor the first column is empty.
