What is the area of a regular polygon with 100 sides and a perimeter of 100 units?

PolarNik [594]

Now, if the regular polygon has 100 sides, and the perimeter is 100 units, that simply means that each side is 1 unit, foot, meter, else.

so, we know each side is 1 unit long, and we know there are 100 sides,

$\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{4}ns^2cot\left( \frac{180}{n} \right)\quad 
\begin{cases}
n=\textit{number of sides}\\
s=\textit{length of a side}\\
\frac{180}{n}=central~angle\\
\qquad~~ in~degrees\\
----------\\
n=100\\
s=1
\end{cases}
\\\\\\
A=\cfrac{1}{4}\cdot 100\cdot 1^2\cdot cot\left( \frac{180}{100} \right)\implies A=25cot\left(\frac{9}{5}^o \right)
\\\\\\
A\approx 795.51289884$

lewis has a bucket with a 5 gallon capacity. lewis puts 12 pints of soapy water in the bucket to wash his car. how many gallons

Tasya [4]

12 pints of soapy water.

8 pints = 1 gallon.

1 pint = 1/8 gallon

12 pints = 12*(1/8)

12 pints = (12/8) gallons

= 3/2 = 1.5 gallons.

Since the bucket is 5 gallon capacity, It can hold:

5 - 1.5

= 3.5 gallons more.

But 1 gallon is = 4 quarts.

3.5 gallons = 3.5 * 4 = 14 quarts more.

Which of the following is not a way to represent the solution of the inequality 8x - (5x + 4) greater than or equal to -31?

n200080 [17]

The response is
x greater than or equal to -9
proof
8x - (5x + 4)>= -31, 3x- 4>= -31, 3x >= -27, x>= -27/3= -9
so x greater than or equal to -9
