What is the formula to 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 formula for finding the area of a regular octagon?
A= 2(1 + sqrt2)S² where S is a side length
Which is the measure of one interior angle of a regular octagon?
If the Octagon is regular use the formula (n+2)180 so 8+2=10*180=1800/8= 225 degrees.
How do you find the measure of degrees of a octagon?
Octagon = 8 sides, 8 angles. If it is a regular octagon, then use the sum of angles formula, (n - 2)180°, where n is the number of sides. (n - 2)180° = (8 -2)180° = 6 x 180° = 1,080° Thus each angle is 135° (1,080/8).
How many diagonals does a octagon have?
20 diagonals For any n-sided polygon, the formula for the number of diagonals is (n/2) x (n-3), so for an octagon it is (8/2) x (8-3) = 4 x 5 = 20.
What is the formula for an octagon?
There is no formula for an octagon. There are formulas for figuring out different aspects of an octagon, such as its perimeter, diameter, etc.
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.
What is the interior angle for a perfect octagon?
To work out the angle of any 'perfect shape' you use this formula: interior angle =((number of sides - 2) x 180)/ number of sides for an octagon: interior angle =((8-2) x 180 )/ 8 = 135 degrees
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)
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
