10. The perimeter of a regular nonagon is 162 inches. The apothem is 97.8 inches. Find the area.

Katen [24]

Answer:

The area of the regular nonagon is 7921.8 square inches.

Step-by-step explanation:

Geometrically speaking, the area of a regular polygon is determined by following area formula:

$A = \frac{p\cdot a}{2}$ (1)

Where:

$A$ - Area of the regular polygon, in square inches.

$p$ - Perimeter, in inches.

$a$ - Apothem, in inches.

If we know that $p = 162\,in$ and $a = 97.8\,in$ , then the area of the regular nonagon is:

$A = 7921.8\,in^{2}$

The area of the regular nonagon is 7921.8 square inches.

4/9 / 9/5= the answer is

mr Goodwill [35]

Answer:

20/81

Step-by-step explanation:

Without parentheses, it is hard to tell what you are dividing. We assume you want ...

(4/9)/(9/5)

Then ...

$\displaystyle\frac{\left(\frac{4}{9}\right)}{\left(\frac{9}{5}\right)}=\frac{4}{9}\cdot\frac{5}{9}=\frac{4\cdot 5}{9\cdot 9}=\frac{20}{81}$

_____

As written (without parentheses), your expression is evaluated left to right, so evaluates to ...

4/(9·9·5) = 4/405
