Answer:
Area of the regular dodecagon inscribed in a circle will be 27 square units.
Step-by-step explanation:
A regular dodecagon is the structure has twelve sides and 12 isosceles triangles inscribed in a circle as shown in the figure attached.
Since angle formed at the center by a polygon =
Therefore, angle at the center of a dodecagon = = 30°
Since one of it's vertex is (3, 0) therefore, one side of the triangle formed or radius of the circle = 3 units
Now area of a small triangle =
where a and b are the sides of the triangle and θ is the angle between them.
Now area of the small triangle =
=
Area of dodecagon = 12×area of the small triangle
= 12×
= 27 unit²
Therefore, area of the regular octagon is 27 square unit.
Answer:
53
Step-by-step explanation:
By examining the numbers and evaluating how the pattern changes, you should have 53 as the upcoming number after 26.
So,
6, 13, 26, <u>53</u>
Answer:
AB ≈ 35.93
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos3.5° = = =
Multiply both sides by 36
36 × cos3.5° = AB, thus
AB ≈ 35.93 ( to 2 dec. places)
