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 Learning(Pls Help ASAP) ( If you don't know don't Answer) Giving 10 points for 2 answers

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

2nd one drag 3rd one
1 one drag 1 one
Step-by-step explanation:
The answers to the questions are given below.
What is a expression? What is a mathematical equation? What is the volume of a cube and a prism?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. The volume of a cube is - [V] = a x a x awhere [a] is side length of cube.
The volume of a prism is -[V] = [h] × [w] × [L]where [h] is prism height, [w] is its width, and [L] is its length.
We have the question as shown in the figure.
Cube with side length (1/5) :
Volume = (1/5 x 1/5 x 1/5) = 1/125 cm³
Prism of dimensions (L = 1/5, B = 2/5, H = 3/5) :
Volume = (1/5 x 2/5 x 3/5) = 6/125 cm³
Cube with side length (2/5) :
Volume = (2/5 x 2/5 x 2/5) = 8/125 cm³
Prism of dimensions (L = 3/5, B = 4/5, H = 3/5) :
Volume = (3/5 x 4/5 x 3/5) = 36/125 cm³
Therefore, the answers to the questions are given above.

D.
Ages: 18, 19, 19, 20, 20, 20, 21, 21, 22, 26
Answer: It would be A
Step-by-step explanation:
First: Find Median
18,19,|19|,20,|20,20|,21,|22|,22,26
there is 10 numbers so it would be between 20 and 20. Add 20 and 20 and you will get 40 and divide by 2 to get 20. Your median is 20 and the dot should be on top of the 20.
Second: Find Quartile 1 and 3
Since it’s 5 numbers on each side, the math is friendly. So you count the first 2, then circle the next number and count the last 2. The one you circled is your Quartile 1 and do the same for Quartile 3. Q1 should be 19 and Q3 should be 22. Check if they are underneath that number you got.
Last: now you know that you just have to find the median and the Q1 and Q3 and you should get the answer which is A.
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
