How do you find the area of a 8 sided polygon?
If the shape is a polygon and it has eight sides, we call it an octagon. To find the area of an octagon we use the following formula. Area of octagon formula = 2 × s2 × (1+√2).
What is an 8 sided box called?
octagon
In geometry, an octagon (from the Greek ὀκτάγωνον oktágōnon, “eight angles”) is an eight-sided polygon or 8-gon….Octagon.
| Regular octagon | |
|---|---|
| Internal angle (degrees) | 135° |
| Dual polygon | Self |
| Properties | Convex, cyclic, equilateral, isogonal, isotoxal |
How do you find out the area of a polygon?
The formula to calculate the area of a regular polygon is, Area = (number of sides × length of one side × apothem)/2, where the value of apothem can be calculated using the formula, Apothem = [(length of one side)/{2 ×(tan(180/number of sides))}].
How do you figure concrete for an octagon?
Just follow these steps:
- Measure the area in feet.
- Multiply length by width, and then by thickness.
- Divide the resulting number by 27 to find cubic yards.
Does an octagon have 8 equal sides?
A regular octagon is a closed shape with sides of equal length and interior angles of the same measurement. It has eight symmetric lines and rotational equilibrium of order 8. The interior angle at each vertex of a regular octagon is 135°. The central angle is 45°.
What is the formula for area of regular polygon?
The area of a regular polygon is one-half the product of its apothem and its perimeter. Often the formula is written like this: Area=1/2(ap), where a denotes the length of an apothem, and p denotes the perimeter.
What can a regular polygon calculator be used for?
Regular polygon calculator is an online tool to calculate the various properties of a polygon. It can be used to calculate the area of a regular polygon as well as various sided polygons such as 6 sided polygon, 11 sided polygon, or 20 sided shape, etc. It reduces the amount of time and efforts to find the area or any other property of a polygon.
How to find the area of an octagon by hand?
If you want to know how to find the area of a regular octagon by hand, the easiest procedure is to apply the standard formula for the area of a regular polygon. The formula is the following: where the apothem is the distance for the center of the polygon to the mid-point of a side.
How to calculate the polygon area of an apartment?
This is useful for apartment renovation, for example, cause at home, it is easier to measure lengths than to measure angles. To calculate the polygon area, you measure side lengths, put them into the table below, then split the polygon into non-overlapping triangles, measure needed diagonals, put them into the table, and you’re done.
How do you calculate the sides of a polygon?
Select the property of polygon from the given list that you want to calculate. Select the given value form the list. Enter the number of sides of the polygon in the given input box. Enter the measurement of the outer side of the polygon. Press the Calculate button after entering all values.
