The ? of a right triangle are the sides that are adjacent to the right angle.
i dont understand someone plz help
Answer:
V = 1815.8 mm^3
Step-by-step explanation:
Okay so this is a tricky one, thats why i decided to help. The first thing you need to do is find the volume of the hemisphere, the formula to do this is 2TTr3 / 3. when you input the values, solve, and round to the nearest tenth you get approximately 718.4 mm^3. The next step is to find the volume of the cone, the formula for volume of a cone is πr^2h/3. When you input the values, solve, and round to the nearest tenth you get approximately 2534.2 mm^3. The third and final step is to subtract the volume of the hemisphere from the volume of the cone, and when you do that you get V = 1815.8 mm^3.

SOLVE FOR VOLUME
Answer:
volume = area of triangle * height = 12.124355653*14/2 * 20 = 1697.40 m3
Step-by-step explanation:
the triangle is equilateral triangle ->
a^2 = 14^2 - 7^2 = 147
-> a = 12.124355653
volume = area of triangle * height = 12.124355653*14/2 * 20 = 1697.40 m3
Answer:
[tex]196meters^2[/tex]
Step-by-step explanation:
The formula for the area of a triangle is : [tex]\frac{base*height}{2}[/tex]
To work this out you would first have to work out the area of the triangle. You can do this by multiplying the base of 14 by the height of 14, this gives you 196.
The next step is to divide the answer of 196 by 2, this gives you 98. This is because the formula is the same as that for the area of a square and that a triangle would be half of a square with the same dimensions.
The final step is to multiply 98 by the length of 20, this gives you 1960 meters cubed.
1) Multiply 14 by 14.
[tex]14*14=196[/tex]
2) Divide 196 by 2.
[tex]196/2=98[/tex]
3) Multiply 98 by 20.
[tex]98*20=196meters^2[/tex]
Kyleigh put a large rectangular sticker on her notebook.the height of the sticker measures 10 cm. the base is half as long as the height. what area of the notebook does the sticker cover?
Hey there! Welcome to Brainly! I'm happy to help you!
When we are talking about the height and base, let's use the variables h and b. With the information we have been given, we can make the following equations below.
h=10 (the height is 10)
b=h/2 (base is half as long as the height)
We see that h is equal to ten. b is equal to h divided by two, so it is therefore ten divided by 2! We take the value for h and the plug it into the second equation!
b=10/2
b=5
So, we now know that the height is 10 cm and that the base is 5 cm. However, we need to find the area. To find the area of a rectangle, we just multiply the base by the height!
10(5)=50
Therefore, the area of the sticker is 50 cm².
I hope that this helps! Have a wonderful day!

Ellen’s dog has a pen that is 32 feet by 33 feet. What is the area of the dog pen? A rectangle with length 3 cubed feet and width of 3 squared feet. Find the area. 1. Multiply powers: 32 · 33 2. Expand each power: (3 · 3) · (3 · 3 · 3) 3. Simplify: 35 Complete each sentence. The of the original exponent is the exponent in the power of product. The dog pen has an area of square feet.
Answer:
3^5 = 243 square feet
Step-by-step explanation:
Ellen’s dog has a pen that is 3² feet by 3³ feet. To find its area we follow the next steps:
1. Multiply powers:
A = 3² * 3³
2. Expand each power:
A = (3*3) * (3*3*3)
3. Simplify:
[tex]A = 3^5[/tex]
The addition of the original exponents is the exponent in the power of product. The dog pen has an area of [tex]3^5[/tex] square feet.
The area of Ellen's dog pen is [tex]\bold{3^5}[/tex]square feet.
The complete sentences are actually the way to solve the question and can be completed as mentioned below:
A rectangle with a length of 3 cubed feet and a width of 3 squared feet.
Find the area.
1. Multiply powers: Area = 3² · 3³
2. Expand each power: Area = (3 · 3) · (3 · 3 · 3)
3. Simplify: Area = [tex]\bold{3^5}[/tex]
The addition of the original exponents is the exponent in the power of the product. The dog pen has an area of [tex]\bold{3^5}[/tex] square feet.
Hence, the area of Ellen's dog pen is [tex]\bold{3^5}[/tex]square feet.

A cylinder and its dimensions are shown. Which equation can be used to find V, the volume of the cylinder in cubic centimeters?
A) V = π(3.5h)2
B) V = π(7h)2
C) V = π(3.5)2h
D) V = π(7)2h
Answer:
The volume of a cylinder is given by the equation:
V = π(R)^^2*h
where π = 3.14, R is the radius and h is the height.
If in the image we see that the radius is 7, then the correct option is D.
If in the image we shee that the DIAMETER is 7 (a linea that goes from end to end of the circle and goes trough the middle) then we know that the radus is half of the diameter, 7/2 = 3.5
in this case he correct option is C.
Answer:
There is no image included, so I cannot give a direct answer. However, you should be able to figure out the answer after my explanation.
Step-by-step explanation:
‼️now pay attention in order to get this question correct‼️
Well, this is a simple problem, since you don’t necessarily need to solve it. First, you need to know the formula of volume for a cylinder. This is: V = πr²h.
Figure out π. Π is a number too long to be written, so we found it up to 3.14.
π = 3.14
Now figure out the radius, for r. This, isn’t my problem to solve because I don’t have a picture of the cylinder so I cant determine so.
The equations don’t specify any height written, so we don’t have to solve for h yet.
This is your job now. So far, I’ve only figured out π, now find the radius, take that number, and fit it in the parentheses. V = π(_)²h. That’s it. Now look at the options, and pick the option that matches what you’ve already written.
I hope I’ve helped, taking time to write this... but I hope you wouldn’t mind brainliest lol c: take care and have a nice day!

Find the volume of the composite figure below:
5 in
8 in
6 in
10 in
Answer:
716in³
Step-by-step explanation:
The first step is to split the full prism into two, separate prisms. That means, we now have to find the volume of the half-a-cylinder, and the other base prism.
For the volume of the half-cylinder, we use the formula πr²h. That means, we do π·5·5·6, which is equal to around 471.24 cubic inches. However, we need to find the volume of half that cylinder, so we divide that answer by two. That should be about 235.62 cubic inches.
For the volume of the other prism, we simply have to do length times height times width, or 6·8·10. That is equal to 480 cubic inches, which is the volume of that prism.
To find the volume of the whole composite figure, you simple have to add the two underlined volumes above.
235.62+480= 715.62in³, or about 716in³.

Answer:
ZY = 14, SQ= 28
Step-by-step explanation:
Because of "ZR=ZS" and "YR=YQ", so we can apply the Thales theorem:
[tex]\frac{x+2}{3x-8}=\frac{RZ}{RS} =\frac{1}{2} \\[/tex]
so 2(x+2)= 3x-8
2x+4 = 3x-8
2x-3x= -8 -4
-x = -12
or x =12
ZY = x+ 2 = 12+ 2 = 14
SQ= 2*ZY= 2*14 = 28
