A regular heptagon has a radius of approximately 27.87 cm and the length of each side is 24.18 cm. what is the approximate area

aniked [119]

The area of the regular heptagon which has a radius of approximately 27.87 cm and the length of each side is 24.18 cm is 2125 cm².

<h3>What is the area of a heptagon?</h3>

Heptagon is the closed shape polygon which has 7 sides and 7 interior angles.

The area of the regular heptagon is found out using the following formula.

$A=\dfrac{7a}{4}\cot \left(\dfrac{180}{7}\right)$

Here, (<em>a</em>) is the length of the heptagon.

A regular heptagon has a radius of approximately 27.87 cm and the length of each side is 24.18 cm. Put the value of side in the above formula,

$A=\dfrac{7\times24.18}{4}\cot \left(\dfrac{180}{7}\right)\\A\approx 2125\rm\; cm^2$

Hence, the area of the regular heptagon which has a radius of approximately 27.87 cm and the length of each side is 24.18 cm is 2125 cm².

If u bring 10 empty bottles to the bottle shop, the bottle shop will change 10 empty bottles to 1 drink. If u bring 100 bottles

expeople1 [14]

<span>In order to calculate this, we can set up a simple ratio. We say that 10 empty bottles : 1 drink 100 empty bottles : x drinks We cross multiply to form the equation: 10x = 100 Now, we can simply solve for x to determine the number of drinks we would get for 100 bottles. x = 10 So we will get 10 drinks if we bring 100 bottles to the bottle shop.Hope this helps. Let me know if you need additional help!</span>

For their craft project during the first week of camp, the campers used clothespins to make miniature rocking chairs. To make 90

fenix001 [56]

1080 clothespins makes 90 chairs and we need to find out how many clothespins it takes to make 1 chair.

We can set up a proportion of the number of chairs to the number of clothespins because of the proportional relationship.

x is the number of clothes pins for 1 chair

$\frac{90 chairs}{1080 clothespins} =\frac{1 chair}{x clothespins}$

Cross multiply to get

90*x= 1080*1

Divide both sides by 90 to isolate x

x = 12 clothespins

It takes 12 clothespins to make 1 chair.
