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.


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.)


If a A regular octagon with sides of length 7 and an apothem of length 8.45 has an area of how many square units?

A = 1/2 * 10.49*7*8 = 293.72


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.)


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.


What are the properties of a regular octagon?

A regular octagon has 8 sides similarly to an octagon. The name regular octagon means that all angles are the same, therefore inferring that all sides are of equal length.


How does a not regular octagon look like?

An octagon has eight sides. A regular octagon is one that has eight sides of equal length, and all the angles are of the same measure. Anything else - sides that are not all the same length, or not all angles the same - would be a non-regular octagon.
