**Find the area of an octagon inscribed in a circle? Yahoo**

Note that a regular octagon looks like this (Wikipedia): So, the triangles in the diagram are isosceles with side length $1$, and their area is given by $\frac{1}{2} (1)^2 \sin (45^\circ)$. There are 8 such triangles, multiply this by $8$ to get the overall area.... Divide the area of the polygon by the number of sides the polygon has. For example, if the area of a square is 36, you would divide 36 by 4 and get 9. Sciencing Video Vault . Divide pi by the number of sides in the polygon. In this example, you would divide pi, about 3.14, by 4, the number of sides in a square, to get 0.785. Use your scientific calculator to calculate the tangent of the result

## How To Find The Area Of An Octagon With Tangent

### Area of an Octagon Box If you happen to know the length of a regular side of an octagon box, meaning all the sides are of the same length, then you can quite easily find the area of the octagon.

- In this section, we will learn how to calculate the area of an octagon. We will also derive a formula for the same and solve some examples so as to give you a clear understanding of the concept. We will also derive a formula for the same and solve some examples so as to give you a â€¦
- This paper looks at comparing the perimeter and area of inscribed and circumscribed regular polygons. All constructions will be made with circles of radius equal to 1 unit.
