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 7 and an apothem of length 10.49 has an area of?

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


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.


How do you find the perimeter of a regular polygon with the apothem and area?

Perimeter = 2*Area/Apothem.


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.


What is the area of a regular octagon with a side of 6.5 and an apothem 5?

130 to find the area of any regular polygon, multiply the perimeter by one-half the apothem. This is the same as multiplying the side-lengths by the number of sides by one-half the apothem.

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)


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.)


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.)
