What is the formula for finding the area of a regular polygon with perimeter P and apothegm length a?
Area of regular polygon: 0.5*apothem*perimeter
A regular octagon with sides of length 7 and an apothem of length 8.45 has an area of how many square units?
By Apothem LengthThe area of a regular octagon can also be computed using its measured apothem (a line from the center to the middle of any side). The formula for an octagon with side length s and apothem a is Area = a4s (apothem times one-half the perimeter)So for this example, (7 cm and 8.45 cm) Area = (8.45)(28) = 236.6 cm2----By Side LengthThe area of a regular octagon with side length s is given as Area = 4.828427 s2 , so for a regular octagon of side length 7 cm , the area is also about 236.6 cm2.(This formula is generated by adding or subtracting the missing corner triangles.)
How does the formula of a octagon work?
There is insufficient information for us to answer this question. Please edit the question to include more context or relevant information. What formula of an octagon are you referring to: the sum of the interior angles, the frustum of a regular octagon, the area, the perimeter, the number of diagonals? The possibilities are almost endless!
A regular octagon with sides of length 8 and an apothem of length 9.66 has an area of how many square units?
By Apothem LengthThe area of a regular octagon can also be computed using its measured apothem (a line from the center to the middle of any side). The formula for an octagon with side length s and apothem a is Area = a4s . (apothem times one-half the perimeter)So for this example, (8 cm and 9.66 cm) Area = (9.66)(32) = 309.12 cm2----By Side LengthThe area of a regular octagon with side length s is given as Area = 4.828427 s2 , so for a regular octagon of side length 8 cm , the area is calculated as 309.02 cm2. (indicating an error from rounding the apothem length)(This formula is generated by adding or subtracting the missing corner triangles.)
What is the area of a regular octagon with an apothem of 8.5?

How do you find the area of an octagon?
The formula for the area of a regular octagon is:A = 2 (1+ SQRT(2)) s**2 , orA = 4.8284 s**2where A= the area of the octagon, ands is the length of one side s**2 indicates s squared or s times s
What is the area of a regular octagon?

Which figure's area formula is most similar to the area formula for a parallelogram?
Octagon
What is the formula to find the volume of an octagon?
You don't find the "volume" of a flat figure. Perhaps you want its surface area.The area for a regular octagon of side "a" is 2 (1 + root(2)) a2, where "root" isthe square root function. If it is not a regular octagon, I don't think there is asimple formula to find the area - you'll have to split it up into simpler figures,for example triangles.==================================Answer #2:Here is the formula, to which the first answer alluded in passing,but which, for some reason, it did not explicitly present:Volume of an Octagon = 0 .

What is the area of a 3 cm sided octagon?
If you mean the area of a regular octagon with 8 equal sides of 3 cm then by using trigonometry its area works out as 43.36 square cm rounded to two decimal places.
What is the perimeter of an octagon that has an area of 43560 sq ft?
The area of a polygon is not enough to determine its shape - unless it is a regular polygon. There is nothing in the question to suggest that the octagon is regular.
Is the formula for finding the area of an oval the same as the formula for finding the area of a circle?
No because the formula for finding the area of an oval, which is an ellipse, is quite different
