What is the area of major sector DFE?
A. 157.86 square cm
B. 133.94 square cm
C. 132.54 square cm
D. 125.57 square cm
Answers
Answer:
Step-by-step explanation:
Area of the circle = πr² = π7.3² = 53.29π
Area of major sector = 53.29π(285/360) ≈ 132.54 cm²
The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.
What is a Major Sector ?The region bounded by the two radii and intercepted arc in a circle is called a sector .
The angle made by the radii to the center of the circle is called central angle .
if the measure of the angle is less than 180 degree then it is called minor sector and if the angle is more than 180 degree , it is called Major Sector.
It is given that
The radii of the circle is 7.3 cm
The angle subtended by the major sector at the center is 285 degree.
The area of the sector is given by
= ([tex]\rm \theta[/tex] / 360) * Area of the circle
Area of the circle is πr²
Area of the sector = ( 285 / 360) * (22/7) * (7.3)²
Area of the sector is 132.5 sq.cm
Therefore , The area of major sector DFE is 132.5 sq.cm , Option C is the right answer.

1. Rafael stands 55 feet from the tower and uses a clinometer to measure the angle of elevation to the
viewing platform as 37º. How far up the tower is the viewing platform?
Answers
Answer:
41.4feet
Step-by-step explanation:
Using the SOH CAH TOA identity
Given the following
Distance of Rafael from the tower = 55feet = Adjacent
Angle of elevation = 37degrees
Required
Height of the tower = Opposite
Since Tan theta = opp/adj
Tan 37 = x/55
x = 55tan37
x = 55(0.7536)
x = 41.4
Hence the tower is 41.4feet up the viewing platform

Answers
Step-by-step explanation:
<c =90 °
So, Pythagoras theorem can be used,
Hypotenuse ² = base ² + altitude ²
AB²=AC²+BC²
11²=AC²+4²
11²-4²=AC²
121-16=AC²
Root 105=AC
AC=10.2 cm
The length of AC is 10.25 cm
What is pythagorean theorem ?
If ΔABC is a right angle triangle, then
AB² = BC²+AC²
where AB = Hypotenuse, BC & AC are adjacent sides of the right angle
What is the required length of the side ?Given, hypotenuse = AB = 11 cm
One of adjacent sides = BC = 4 cm
We have to find the length of AC.
Using pythagorean theorem,
AB² = BC²+AC²
⇒ AC² = AB² - BC²
⇒ AC² = 11²-4²
⇒ AC² = 121-16
⇒ AC = √105
⇒ AC = 10.25
So the length of AC = 10.25 cm

What is the slope of the line that passes through the points (5,−4) and (7, -4) ?Write your answer in simplest form.
Answers
Answer:
Undefined
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope of the line
[tex] =\frac{ - 4 - ( - 4)}{7 - 5} \\ =\frac{ - 4 + 4}{2} \\ = \frac{0}{2} \\ (undefined)[/tex]
Thus, the slope of the line is undefined.
(Since 2 cannot be divided by zero)
Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.

it's A you're rightAn auditorium has 21 rows of seats. The first row has 18 seats and each succeeding row has 2 more seats than the previous row. How many seats are in the auditorium?
Answers
Answer:
798
Step-by-step explanation:
So, 21*{2*18 + (21-1)*2}/2
= 21*{36 + 20*2}/2
= 21*{36+40}/2
= 21*76/2
= 1596/2
= 798
Total number of seats is 798
Given that;Number of seats in first row = 18
Number of rows = 21
Each row added number of seats then previous = 2
Find:Total number of seats
Computation:Total number of seats = Sn = (n/2)[2a + (n-1)d]
Total number of seats = Sn = (21/2)[2(18) + (21-1)2]
Total number of seats = (21/2)[36 + (20)2]
Total number of seats = (21/2)[36 + 40]
Total number of seats = (21/2)[76]
Total number of seats = (21)(38)
Total number of seats = 798
