Radius of circle = r = 5 cm
Angle made by the arc = Ф = π/4 radians
Area of sector = A = ?
The formula for the area of a sector is:
A = 0.5r²Ф
Using the values, we get:
A = 0.5 x (5)² x π/4
A = 3.125π cm²
Rounded of to nearest tenth, the area of the sector GHJ is 3.1π cm²
Answer:
V = 96 pi m^3
Step-by-step explanation:
V = (1/3) pi(r^2)h
Radius = 1/2(Diameter)
R = 1/2(12)
R = 6
Input.
V = (1/3) pi(6^2)8
Solve.
V = (1/3) pi(36)8
V = (1/3) 904.32
V = 301.44
V = 301.44/pi
V = 96 pi m^3
Let's look at the two denominators:
7= 7
4= 4
LCM(7,4)= 4*7= 28
5/7+ 1/4
= (5*4)/ (7*4)+ (1*7)/ (4*7)
= 20/28+ 7/28 (common denominator is 28)
= 27/28
The final answer is 27/28~
<h2>Answer: 36-gon (also called triacontakaihexagon)
</h2>
Let's start by explaining that a polygon is a closed geometrical figure composed from three or more lines. These lines (sequence of straight segments) are the sides of the polygon, and the points where they intersect are called vertices that form their angles.
It should be noted that its name comes from the Greek word <em>polygōnon</em> (many angles), since the angles (although the sides are used, as well) are those that will define the name the polygon will have.
In this sense, for a polygon that has 36 angles, its name is 36-gon, and formally named as triacontakaihexagon or triacontahexagon (sometimes the Greek word <em>kai</em> that serves as connector, is omitted).
