in a circle with a radius of 7 feet, the radian measure of the central angle subtended by an arc with a length of 4 feet is 0.57 . the area of the sector formed by the arc is square feet. assume π
The area of the sector formed by the arc of the circle is 14 square feet.
What is sector of the circle?A sector of a circle is a pie-shaped section of a circle formed by the arc and its two radii. A sector is formed when a portion of the circle's circumference (as well known as an arc) and two radii cross paths at both endpoints of a arc. A sector of a circle has the shape of a pizza slice or even a pie.
Two radii and an arc encircle a portion of a circle.A circle is divided into two segments which are referred to as minor sectors as well as major sectors.The major sector is represented by the larger portion of the circle, while the minor sector is represented by the smaller portion.Now, according to the question;
Length of a sector is estimated by the formula = ∅×r
where ∅ is the angle formed by sector in radians and r is the radius of the circle.
Thus,
∅ = Length of a sector/r
The radius is r = 7 ft
The value of length of a sector = 4 ft
∅ = 4/7
∅ = 0.57 radians
Now, estimate the area of the sector.
area of a sector = (∅/2)×r²
Substituting the values.
area of a sector = (4/7/2)×7²
= (4/14)×49
area of a sector = 14 ft²
Therefore, the area of the sector is calculated as 14 ft².

Find the volume and surface area.
Answer: Formula used for pyramid is (V= 1/3 Bh SA: 1/2 P*l+B) Final answer is SA=110.4 V=64
Step-by-step explanation:
P= Perimeter
l= length
B= Base
To find the perimeter you add all the sides of the base. (4+4+4+4)=16
To find the length you can use Pythagorean Theorem which is a(squared) + b(squared) = c(squared) where c is the hypotenuse. [tex]2^{2}[/tex] + [tex]12^{2}[/tex]= [tex]x^{2}[/tex]
4+144=[tex]x^{2}[/tex]
164=[tex]x^{2}[/tex]
[tex]\sqrt{164}[/tex]=x
x=12.8
To find the base it will be l*w (4*4)=16
Then you plug it in the formula for SA which will be
SA=1/2 16*12.8+16
SA=110.4
For Volume, it will be
V=1/3 Bh
V= 1/3 16(12)
V= 64

PLEASE HELP ASAP
Answer:
y-intercept: (0, -0.7)
x-intercept: (-1.2, 0)
Step-by-step explanation:
To find the x-intercept (x, 0) of a line substitute y by zero in the equation of the line, and from the graph, it is the point of intersection between the line and the x-axisTo find the y-intercept (0, y) of a line substitute x by zero in the equation of the line, and from the graph, it is the point of intersection between the line and the y-axisIn the given figure
∵ The line intersects the y-axis at the point (0, -0.7)
∴ The point of intersection between the line and the y-axis is (0, -0.7)
→ By using the 2nd note above
∴ The y-intercept is (0, -0.7)
∵ The line intersects the x-axis at the point (-1.2, 0)
∴ The point of intersection between the line and the x-axis is (-1.2, 0)
→ By using the 1st note above
∴ The x-intercept is (-1.2, 0)

Bags of flour come in 3 sizes: Small bag: A 200 g bag costs 40p. Medium bag: A 1 kg bag costs £1.80. Large bag: A 2 kg bag costs £3.80. Calculate the cost of 1 kg for the small and large bags. Give your answer in pounds to 2 dp.
Answer:
Small bag: 1kg cost 200.00p
Large bag: 1kg cost £1.90
Step-by-step explanation:
Small bag: A 200 g bag costs 40p
Medium bag: A 1 kg bag costs £1.80.
Large bag: A 2 kg bag costs £3.80.
Calculate the cost of 1 kg for the small and large bags.
Small bag: A 200 g bag costs 40p
200g cost 40p
1 gram cost 40/200
1 gram = 0.2 p
1000 g = 1kg
1kg cost = 0.2p × 1000
= 200.00p
Small bag: 1kg cost 200.00p
Large bag: A 2 kg bag costs £3.80.
Cost of 1kg = cost of 2kg bag / 2
= £3.80 / 2
= £1.90
Large bag: 1kg cost £1.90

a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6. What is the value of B?
Answer:
B = 2
Step-by-step explanation:
I used Desmos to get a visual representation to help.
The equation y = 4x + 6 has a y - intercept at (6,0).
The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).
Hope this helps!
The value of B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.
What is an equation?
The equation in mathematics is the relationship between the variables and the number and establishes the relationship between the two or more variables.
The equation y = 4x + 6 has a y - intercept at (6,0).
The equation y = 4x + 2 has a y - intercept at (2,0) and passes through (1,6).
Therefore the value of B = 2 when a line, y=mx+b, passes through the point (1, 6) and is parallel to y=4x+6.

Answer:

Step-by-step explanation:
116-98
so sorry if its incorrect
Answer:
34 degrees
Step-by-step explanation:
ahahah okay this is fun
so what you should do here is extend the line that passes through the 116 and 98 degree angle so that it passes the other parallel line.
It makes a triangle doesn't it
One of the angles is supplementary to 98, so 180-98 = 82 degrees.
Another one of the angles is the opposite angle to the supplementary angle of 116 (remember your line-intersecting-parallel-lines angles), therefore 180-116 = 64 degrees
The last angle of that triangle is the opposite to angle 4, and you can find that using the other two angles of the triangle we made earlier, which you get 180-82-64 = 34 degrees
