How many diaganls does an octagon have?
An 8 sided octagon has 20 diagonals according to the formula 0.5*(n^2 -3n) whereas n is the number of sides of the polygon.
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 formula for finding the numbers of diameters of an octagon?
Formula for number of diagonals in an n-sided polygon is: number_of_diagonals = n x (n - 3) / 2 For an octagon, put n=8 in the above to get: number_of_diagonals_in_an_octagon = 8 x (8 - 3) / 2
What is the formula find the area of an octagon?
one way to do it is to first draw a rectangle around the octagon then multiply length by width then subtract the area of the four triangles out side the octagon from your total answer. OR You can use the formula A= 2 s2 cot(π/h) π is supposed to be pi s2 is supposed to be s squared Cot is an abbreviation for cotangent
What is the square footage of an octagon house that has 12 feet sides?
The formula for the area of an octagon is Area = (2 + 2√2)a2, where a is the length of each side. Area = (2 + 2√2)12ft2 = 695ft2
Which figure's area formula is most similar to the area formula for a parallelogram?
Octagon
What is the formula perimeter of regular octagon?
8*length of side.
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!
What is the formula of octagon based pyramid?
Area = ( 2 + 2√2 )a2
How many diaganols has an octagon?
Using the formula: 0.5*(64-24) = 20 diagonals
How do you find the square feet in an octagon?
Assuming it's an octagon with equal sides (s = length of one side in feet) the formula is approximately: Area = 4.8284*(s2)
