The radius of the circle is 17.54 cm
What is the relation between central angle and angle on circumference?Consider an arc of a circle.
Suppose it subtends θ angle on the rest of the part of the circumference (at any point). Then it subtends 2θ angle on the center of that circle.
Given that Chord 12 cm long subtends an angle of 40 degrees at the center of a circle.
θ= 40° = 0.698 radian
Let R be the radius of circle.
Chord Length = 2Rsin(θ/2)
12=2R sin (0.698 /2)
R= 17.54
Hence Radius of circle = 17.54 cm

Answer the question above
Answer:
BA
Step-by-step explanation:
Here, we want to get the hypotenuse side
The hypotenuse represents the longest side
it is the side that faces the largest angle in a right triangle
The largest angle in a right triangle is the right angle which is the angle 90
It is like the square at a corner at the vertex C
The side facing it here is the the length AB (BA)

Frank designed a net for a storage shed that he is going to construct out of metal. The design consists of a square base and four square sides, plus four triangular parts that make up the roof.
He had 250 square feet of metal to use to build the shed. (What is the surface area of the storage Shed that Frank Designed?) (Does Frank have enough metal to construct his design yes or no?)
Answer:
Yes, Frank does have enough, he has 250 metal and only has 228 surface area.
Step-by-step explanation:
You take all the triangles (4) and multipy 4 x 6 (24) then divide that by 2 (12) so now you know all the triangles are equal to 12. Then the squares, you multiply 6 x 6 (36) now you know all the squres are equal to 36 and then you add 12 + 12+12+12+36+36+36+36+36 and then you get 228.

if it wants the measurement of arcJK....
Answer:
ArcJK= 128
Step-by-step explanation:
Circle is 360 degrees
<KL is the diameter which is a straight line equals 180 degrees
Since <KLis also a central angle arcKL equals 180
Take <K (26) and times by two cause its an inscribe angle, 26*2=52
arcJL=52
add both arcKL and arcJL together: 180+52=232
then you take 360-232=128
and 128 is KLarc

pleaseeeeee show the work
Answer:
I got x=10
Step-by-step explanation:
Step 1
Everything must add up to 180
180= 6x - 6 + 7x + 1 +55
Step 2
Combine everything
6x + 7x = 13x
-6 + 1 +55 =50
180 = 13x + 50
Step 4
Subtract. 180 -50
130 = 13x
Step 5
Divide 130/13
X=10
6(10) -6 = 54
7(10) + 1=71

Manuel bought 9 pounds of apples.
He has eaten 3
4 of a pound so far and has
$15 worth of apples left. Write and solve an
equation to find the cost of the apples per
pound to the nearest dollar. How much did
the apples cost per pound?
Answer:
1) Since Manuel bought 9 pounds and ate 3/4 of 1 pound, he has 8.25 pounds left (9 - 0.75 = 8.25)
2) Let's call "x" the cost of 1 pound of apples
3) (8.25)*(x) = $15
4) x = $1.81818 rounded to the nearest dollar is $2 / pound
Is 0.3 the multiplicative inverse of 3 1/3? Why or why not?
Chapter : Rational Numbers
Answer:
3 1/3 = 10/3
0.3 = 3/10
a * 1/a =1
then 1/a is multiplicative inverse of a
0.3* 3 1/3 = 3/10 * 10/3 =1
0.3 is multiplicative inverse of 3 1/3
Step-by-step explanation:
Answer:
3 1/3 = 10/3
10.3 = 0.3 = 3 1/3
x * 1/x = 1
∴ yes, the multiplicative reverse of 3 1/3 is 0.3

in a class room 1/6 of students are wearing blue shirts 2/3 are wearing white shirts there are 12 students how many are wearing shirts other than blue shirts?
Answer:
4 students
Step-by-step explanation:
what we know: 12 students, 2/3 are wearing blue, 1/6 are wearing red
first you have to make the fractions have the same denominator(2/3=4/6)
theres also 1/6 that are not wearing blue or red (1/6+4/6=5/6, 6/6-5/6=1/6)
so that makes it 2/6 of the students not wearing blue(1/6+1/6=2/6)
simplify(2/6=1/3)
1/3 of 12 is 4 (12÷3=4)
the equations are in parentheses and bolded, italicized, underlined.

i have to determine if DE is parallel to AC
Answer:
Triangle BDE and triangle BAC are similar triangles
Hence, two lines DE and AC are parallel to each other
Step-by-step explanation:
For proving that DE is parallel to AC, we are required to prove that triangle BDE and triangle BAC are similar triangles
The ratio of sides of both the triangle must be equal to each other
Hence
[tex]\frac{BE}{DB} = \frac{BC}{BA} \\\frac{16.1}{28} = \frac{20.7+16.1}{64}\\0.575 = 0.575[/tex]
and angle B is common.
Hence the two triangles are similar.
Therefore angle BDE and angle BAC are equal like wise angle BED and angle BCA are equal.
Thus, the two lines DE and AC are parallel to each other

An architect is recreating the blueprint for a deck with an existing scale factor of 1 in. equals 2 ft, that is shown. The architect is using a different scale so that the length of the same deck on the new blueprint measures 8 inches. Complete parts a and b. What is the scale factor of the new blue print? 1 inch = ______feet.
Part 2: What is the width of the deck on the new blueprint?
Answer:
[tex](a)\ k_2 = 1in:3ft[/tex]
[tex](b)\ Scale\ width =\frac{16}{3}\ in[/tex]
Step-by-step explanation:
Given
[tex]k_1 = 1in : 2ft[/tex] --- Initial scale factor
[tex]Blueprint: 12in\ by\ 8in[/tex] --- Missing from the question
Solving (a): The new scale factor.
Convert the initial blueprint to actual measurement using the initial scale factor, we have:
[tex]Length = 12 * 2ft = 24ft[/tex]
[tex]Width = 8 * 2ft = 16ft[/tex]
From the question, we understand the new scale factor represents the width as 8in.
The scale factor (k2) is then calculated as:
[tex]k_2 = \frac{Scale\ length}{Actual\ length}[/tex]
[tex]k_2 = \frac{8in}{24ft}[/tex]
Simplify
[tex]k_2 = \frac{1in}{3ft}[/tex]
Represent as fraction
[tex]k_2 = 1in:3ft[/tex]
The above is the new scale factor
Solving (b): The new width
Using the scale factor above we have:
[tex]k_2 = \frac{Scale\ width}{Actual\ width}[/tex]
[tex]\frac{1in}{3ft} = \frac{Scale\ width}{16ft}[/tex]
The 16 is gotten from:
[tex]Width = 8 * 2ft = 16ft[/tex]
So, we have:
[tex]Scale\ width = 16ft * \frac{1in}{3ft}[/tex]
[tex]Scale\ width = 16 * \frac{1in}{3}[/tex]
[tex]Scale\ width =\frac{16\ in}{3}[/tex]
[tex]Scale\ width =\frac{16}{3}\ in[/tex]
Hence, the scale width of the blueprint is: 16/3 inches
Answer: Part A is 3 and part b is 5 1/3 inches
