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
Answers
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.

Answer:
The letter 'E' has exactly one line of symmetry passing from it's center.
Step-by-step explanation:
We are given the letter 'E' for checking whether it have symmetry.
For that, first of all let us understand what does line of symmetry means;
A line of symmetry is a line that separates an object into two identical sections that are mirror images of one another.
Now,
The letter 'E' has exactly one line of symmetry passing from it's center.
Furthermore, just like the letter 'E' various other letters also have exactly one line of symmetry.
For example, Letter A, B, C, D, E, K, M, have exactly 1 line of symmetry.

Find the volume and surface area.
Answers
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

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

Answer:
x = 5
Step-by-step explanation:
Solve for x:
-1 - 5 (-x - 1) + 4 x = 49
-5 (-x - 1) = 5 x + 5:
(5 x + 5) + 4 x - 1 = 49
Grouping like terms, 5 x + 4 x - 1 + 5 = (5 x + 4 x) + (-1 + 5):
((5 x + 4 x) + (-1 + 5)) = 49
5 x + 4 x = 9 x:
9 x + (-1 + 5) = 49
5 - 1 = 4:
9 x + 4 = 49
Subtract 4 from both sides:
9 x + (4 - 4) = 49 - 4
4 - 4 = 0:
9 x = 49 - 4
49 - 4 = 45:
9 x = 45
Divide both sides of 9 x = 45 by 9:
(9 x)/9 = 45/9
9/9 = 1:
x = 45/9
The gcd of 45 and 9 is 9, so 45/9 = (9×5)/(9×1) = 9/9×5 = 5:

Answers
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
