The correct statements about the volume of the cone are:
- The volume of the cone is One-third the volume of the cylinder.
- The expression 84 pi over 3 finds the volume of the cone.
- The volume of the cone is less than the volume of the cylinder.
What is the volume of cylinder?[tex]V=\pi\times r^2\times h[/tex]
where 'r' is the radius of the base of the cylinder and 'h' is height of the cylinder
What is the volume of the cone?[tex]V=\pi\times r^2\times \frac{h}{3}[/tex]where 'r' is the radius of the base of the cone and 'h' is height of the cone
For given example,
The volume of the cylinder is 84 pi inches cubed.
Let [tex]V_1[/tex] represents the volume of the cylinder.
[tex]V_1=84~~cu.in.[/tex]
Using the formula of the volume of the cylinder,
[tex]V_1=\pi\times r^2\times h[/tex]
where 'r' is the radius of the base of the cylinder and 'h' is height of the cylinder
Let [tex]V_2[/tex] be the volume of the cone.
Assume that the base radius 'r' and height 'h' of the cone and the cylinder are equal.
Using the formula of the volume of the cone,
[tex]\Rightarrow V_2=\pi\times r^2\times \frac{h}{3}\\\\\Rightarrow V_2=\frac{1}{3}\times( \pi\times r^2\times h) \\\\\Rightarrow V_2=\frac{1}{3}\times V_1[/tex]
This means, the volume of the cone is One-third the volume of the cylinder.
[tex]\Rightarrow V2=\frac{1}{3}\times 84[/tex]
This means, the expression 84 pi over 3 finds the volume of the cone.
[tex]\Rightarrow V_2=28~~cu.in.\pi \\\\\Rightarrow V_2 < V_1[/tex]
This means, the volume of the cone is less than the volume of the cylinder.
Therefore, the correct statements about the volume of the cone are:
- The volume of the cone is One-third the volume of the cylinder.
- The expression 84 pi over 3 finds the volume of the cone.
- The volume of the cone is less than the volume of the cylinder.

t= hours, they traveled 4 1/2 hours, or 4.5 hours, so t= 4.5
The expression is 65t, so putting in the 4.5, its
65(4.5), 65 x 4.5= 292.5
So, the answer is 292.5
What is the answer to this equation?
1/2 (4i+8)=-2
Answer:
If your looking for I the answer is -3
Step-by-step explanation:
Simplify both sides of the equation
1/2(4i+8)=-2 - Distribute
(1/2) (4i) + (1/2) (8) = -2
The subtract 4 from both sides
Then divide both sides by 2

Answer:
120
Step-by-step explanation:
The formula for a triangle is 1/2bh
so u first multiply 12 by 20 which you will get 240.
After you get 240 u multiply it by the 1/2 which also means dividing by 2.
240 divided by 2 is 120.

I need help ASAP find u and v
Answer:
u = 66
v = 38
Step-by-step explanation:
In a parallelogram, opposite angles are equal. U is opposite to 66, so it is 66 degrees
In a parallelogram, corresponding angles are supplementary. 180 - 66 = 114
this means that 3v = 114. 114/3 = 38, which is what v is.

consider a rectangular prism with length 4 and width and height d
Find an expression for the volume of the prisms in terms of d.
2. compute the volume of the prism when d=1, when d=2, and when d=1/2
Answer:
Step-by-step explanation:
The expression for the volume of the prisms in terms of d is 4d².
What is a volume?Volume is the amount of space occupied by a three dimensional shape or object. For a rectangular prism:
Volume = length * width * height
From the diagram, length = 4, width = d, height = d. Hence:
Volume = 4 * d * d = 4d²
When d = 1: Volume = 4(1)² = 4
When d = 2: Volume = 4(2)² = 16
When d = 1/2: Volume = 4(1/2)² = 1
The expression for the volume of the prisms in terms of d is 4d².

Answer:

Step-by-step explanation:
119 is adjacent to angle x. angle x and 119=180 (because the angle of a straight line is 180.) which means to find angle x you have to subtract 119 from 180. 180-119=61. because you now know two angles in the triangle you can add the together and subtract them from 180 (remember 180 is what all the angles in a triangle should add up to 180). 61+57=118 and 180-118=62

A DVD rental service wants to pay close attention to what movies their customers like the most. Which measure of central tendency will give them the best estimate? Explain.
Answer:
Mode.
Because it is used to determine the most frequently occurring item which in this case is movie.
Step-by-step explanation:
The 3 measure of central tendencies are namely;
Mean, median mode.
- Mean is defined as the average of a set of data.
- Median is the middle term of a set of data that splits that set of data into 2.
- Mode is the term that occurs most frequently in a set of data.
In this question, we want to find the movies most frequently watched.
Thus, from the definitions above earlier, it is clear that the only way to know this is using the mode.

A pair of jeans is normally priced at $56, but is currently marked down for with a 35% discount. What would replace the B in the proportion? A/B=P/100%
Answer:
$36.4
Step-by-step explanation:
Given
Cost of Jean = $56
Percent markdown = 35%
Discount = 35% of $56
Discount = 0.35 * 56
Discount = $19.6
New price = $56 - (35% of $56)
New price = $56 - 19.6
New price = $36.4
hence the price that will replace B is $36.4
F is inversely proportional to d^2. When F=9, d=4 Work out d (positive value rounded to 2 DP) when F=6
Answer:
d = 4.90
Step-by-step explanation:
Given the following data;
F = 9
d = 4
For an inversely proportional relationship, we have;
F = k/d²
Now, we would find the constant, k;
9 = k/4²
k = 9*16
k = 144
Next, to find d, when F = 6
d² = k/F
d² = 144/6
d² = 24
Taking the square root of both sides, we have;
d = 4.90
