Answer:
236 cm^2
Step-by-step explanation:
Formula
Area = sector angle/360 * pi * r^2
Givens
Sector angle = 120
r = 15
Solution
Area = 120/360 * 3.14 * 15 * 15
Area = 1/3 * 3.14 * 225
Area = 235.5
Area = 236 cm^2
Answer:
A regular octagon is a bidimensional figure with eight sides and eight vertices. The words "regular" refers to the equivalence between sides, that is, all sides have the same length.
So, a regular octagon can be described as
- A figure with eight equal sides.
- A figure with eight vertices.
- A polygon.
- A symmetric figure.
The equivalence between sides makes the regular octagon symmetric. Additionally, this figure is a polygon, because it has 8 sides which enclose a region.
