about 30.1775 sq ft.

Apothegm = half side x tan 67.5o

= 1.25 x 2.4142 = 3.01775

Area = 8 x 3.01775 x 1.25

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.


How do you find the area of an octagon with the perimeter of 72 inches?

You cannot. The perimeter alone does not provide enough information unless the octagon is regular and there is no valid reason to assume that it is.


A regular octagon has an apothem measuring 10 in. and a perimeter of 66.3 in. What is the area of the octagon rounded to the nearest square inch?

To find the area of a regular octagon, you can use the formula: Area = (Perimeter × Apothem) / 2. Given the perimeter is 66.3 inches and the apothem is 10 inches, the area calculates to: Area = (66.3 × 10) / 2 = 331.5 square inches. Rounding to the nearest square inch, the area of the octagon is approximately 332 square inches.


What is the area of an octagon with an apothem of 8ft.?

The area of a regular octagon can be calculated using the formula: ( \text{Area} = \frac{1}{2} \times \text{Perimeter} \times \text{Apothem} ). For a regular octagon, the perimeter can be expressed as ( 8 \times \text{side length} ). If the apothem is 8 ft, the area is approximately ( 32 \times \text{side length} ). To find the exact area, you would need the side length, but with just the apothem, the area is typically approximated as ( 32 \text{ ft}^2 ) for a regular octagon.


A regular octagon with sides of length 7 and an apothem of length 10.49 has an area of?

Area in square units = 0.5*(apothem)*(perimeter)


What is the perimeter and the area of a regular octagon with 4 side and apothem a?

If the sides are of length 4 units then the perimeter is 8*4 = 32 units. Its area is then 77.255 square units.


A regular octagon with sides of length 11 and an apothem of length 8.85 has an area of what?

An apothem of a regular polygon is a segment from its center to the midpoint of a side. You can use the apothem to find the area of a regular polygon using this formula: A = pa/2 where p is the perimeter of the figure and a is the apothem. For a regular octagon with side length 11, the perimeter p = 8(11) = 88. So the area would be A = 88(8.85)/2 = 389.4 square units.


The formula for volume of an octagon?

an octagon doesn't have a volume its has and area ecause it is a 2-d figure. to find the area of a 2-d regular figure it is 1/2 apothem * perimeter (apothem is the distance of a line from the center of a polygon, to the midpoint of a side)
