Answer:
44 in.
Step-by-step explanation:
pi = 3.14 (in our case)
circumference = diameter x pi
circ. = 14 x 3.14, which equals to 43.96
round that and you get 44 in.

A cone has a slant height of 7.5cm and a radius of 4.5 cm. What is the volume of the cone?
Now
volume:-
1/3πr²h1/3π(4.5)²(6)π(20.25)(2)40.5πcm³Answer:
Volume of cone = 127.17 cm³Step-by-step explanation:
In the question we are given ,
Slant height = 7.5 cmRadius = 4.5 cmAnd we are asked to find the volume of cone. We know that ,
[tex] \red{\boxed{ \rm{Volume \: of \: cone = \frac{1}{3} \pi r {}^{2}h }}}[/tex]
Where ,
π = 3.14r = 4.5 cmh = Not givenSo , for finding volume of cone we must have to find the height of cone using slant height formula i.e. ,
[tex] \green{\boxed{ \sf{l {}^{2} = h {}^{2} + r {}^{2} }}}[/tex]
Where ,
l = slant heighth = heightr = radiusNow , substituting values :
[tex] \hookrightarrow \: 7.5 {}^{2} = h {}^{2} + 4.5 {}^{2} [/tex]
Transposing 4.5 to left hand side :
[tex] \hookrightarrow \: 7.5 {}^{2} - 4.5 {}^{2} = h {}^{2} [/tex]
[tex] \hookrightarrow \:56.25 - 20.25 = h {}^{2} [/tex]
On further calculations we get :
[tex] \hookrightarrow \:h {}^{2} = 36[/tex]
[tex] \hookrightarrow \:h = \sqrt{36} [/tex]
We know that 6 × 6 is equal to 36 that means square root of 36 is 6 . So :
[tex] \hookrightarrow \pink{\boxed{\bold{h = 6 \: cm}}}[/tex]
Therefore, height of cylinder is 6 cm .Now finding volume :Substituting values in volume formula :
[tex] \longrightarrow\: \frac{1}{ \cancel{3} } \times 3.14 \times (4.5) {}^{2} \times \cancel{6}[/tex]
Step 1 : By cancelling 6 with 3 we get :
[tex] \longrightarrow \: 3.14 \times 20.25 \times 2[/tex]
Step 2 : Multiplying 20.25 with 2 :
[tex] \longrightarrow \:3.14 \times 40.50[/tex]
Step 3 : Multiplying 3.14 with 40.50 :
[tex] \longrightarrow \: \purple{\boxed{\bold{127.17 \: cm {}^{3} }}}[/tex]
Therefore, volume of cone is 127.17 cm³ .#Keep Learningplease help me there is a screenshot attached
Answer:
Area= 372
Step-by-step explanation:
The area of a trapezoid is
[tex]\frac{a+b}{2} * h[/tex], where a is the top base, and b is the bottom base.
A is 7, B=24
h, the height, is the height, which is perpendicular to the bases. The height is 24.
Plug it into the equation,
31/2 * 24 is 372.

3. Find Each Angle Measure
Answer:
m1=125 degrees
m2=55 degrees
m3=55 degrees
m4=125 degrees
m5=125 degrees
m6=55 degrees
m7=55 degrees
Step-by-step explanation:
becoz the image thing says m8 is 125 degrees
and that just gave us the answer for measures 5, 4, and 1 because a is parallel to b so thats why you can see that all of the measures are all the same
now for 2, 3, 6, and 7 we needa find those righht?
remember full circle is 360 degrees and we know measures 4 and 1 is 125 degrees,
so all we gotta do is add them which is 250 degrees and subtract from 360 degrees
360-250 = 110 degrees
ok now divide by 2 since were lookink for 2 and 3 not 2 and 3 combined
110/2=55 degrees
and boom all of those angles are the same for 5, 6, 7, and 8

C = (-4,5) D = (-2,3)
11) 8.426
10) 3, 4, 5
level 3-4) 24
Step-by-step explanation:
11) 7^2 + 11^2 = c^2
49 + 22 = c^2
√71 = √c^2
c = 8.426
10) 3, 4, 5 is a special right triangle but
3^2 + 4^2 = 5^2
25 = 25

Molly is painting a model house and needs to know how much paint she will need. She knows the surface area of the prism is 216 square inches and the surface area of the pyramid is 84 square inches.
1. Which surface is shared by the two solids? What are the dimensions of this surface?
2. There is another surface that Molly does not need to paint, because it won’t show when she displays the model house. Describe that surface, and explain why it doesn't need to be painted.
3. To find the area Molly needs to paint, she should add the surface areas of both solids and subtract:
twice the area of the triangle
twice the area of the square
three times the area of the square
the area of the square
4. Find the area Molly needs to paint. Show your work, and be sure to include units with your answer.

Answer:
1. a square which is 6 × 6in
2. the inside of the prism or cube as it is not seen from the outside
3. the area of the square - 6 × 6 = 36in
4. 6 x 6 = 36 / one face of prism
× 5 = 180
4 × 6/2 = 12 / one face of pyramid

For a science project, Chase recorded the amount of rainfall for 6 weeks. The line plot shows the amounts of rainfall he recorded. How many inches of rainfall were recorded?
Answer: B
Step-by-step explanation:
To answer this , we need to make a list of all the fractions represented with the dots . each dot stands for 1 of whatever fraction is given. for example, there are 2 dots on 3/8 . That means each dot=3/8
3/8, 3/8, 4/8, 5/8, 7/8.
Step 2: Add them up (because we want to find the total)
3/8+3/8+4/8+5/8+7/8= 6/8+4/8+5/8+7/8= 22/8= 2 6/8= 2 3/4
2 3/4 , or 2 6/8 is the answer; it's all the rain that was recorded .
Line plot shows the amounts of rainfall is equals to [tex]2\frac{6}{8}[/tex] inches.
What is line plot?" Line plot is defined as the representation of the data using point on the number line."
According to the question,
Number of weeks for which rainfall is recorded = 6
Data represents on the line plot = [tex]0, \frac{3}{8} ,\frac{3}{8}, \frac{4}{8}, \frac{5}{8}, \frac{7}{8}[/tex]
Total amount of rainfall recorded on line plot in inches
= [tex]0+\frac{3}{8} +\frac{3}{8}+\frac{4}{8}+\frac{5}{8}+ \frac{7}{8}[/tex]
= [tex]\frac{22}{8}[/tex]
= [tex]2\frac{6}{8}[/tex] inches
Hence, Option(B) is the correct answer.
