Answer:

The volume of the cylinder is 3 times the volume of the cone

Step-by-step explanation:

The formula for the volume of the cylinder is given by :

[tex]V_{cy}=\pi r^2 h[/tex] .....(1)

Where

r and h are the radius and the height of the cylinder

The formula for the volume of the cone is given by :

[tex]V_{cone}=\dfrac{1}{3}\pi r^2h[/tex] ...(2)

From equation (1) and (2),

[tex]\dfrac{V_{cy}}{V_{cone}}=\dfrac{\pi r^2 h}{\dfrac{1}{3}\pi r^2 h}\\\\=3\\\\V_{cy}=3\times V_{cone}[/tex]

So, the volume of the cylinder is 3 times the volume of the cone.

Step-by-step explanation:

Answer:

The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m

The equation would be:

144 x 3.14 - 64 x 3.14 = 251.2

Step-by-step explanation:

First, you need to find out what the whole circle is:

The whole circle is 452.16

Then, find the inner circle :

8 x 8 x 3.14  

200.96

Last, subtract the whole by the inner:

452.16 - 200.96 = 251.2

hope this helps!

d=diameter

radius is 1/2 of diameter

The diameter is 9 so the radius is 4.5

Answer:

1253 square inches

Step-by-step explanation:

so first you find the top:

7x5x5=175

then the bottom:

11x14x7=1078

add them and then you get 1253

Answer:

C; 1,253 in

Step-by-step explanation:

7 x 5 x 5=175

11 x 7 x 14=1078

1078 + 175= 1253

Answer:

[tex]W=\sqrt{F}[/tex]

Step-by-step explanation:

The given relation is as follows :

[tex]F=W^2[/tex]

We need to rearrange it to make W the subject.

When square gets removed from W, it goes to F and it will form as follows :

[tex]W=\sqrt{F}[/tex]

Hence, this is the required solution.

Answer:

169 meters

Step-by-step explanation:

52/4=13 (since it's a square you divide it by 4 because the sides are equal, so each side is 13 meters)

13^2=169 (to find the area you square the length of each side)

Answer: ❘-168 - 115❘

you’re finding difference so we set up a subtraction problem.

We can’t have a negative answer so we must take the absolute value of that number

Answer:

Step-by-step explanation:

Answer:

4m² + 11m + 6

Step-by-step explanation:

Use foil to expand this value.

(4m+3)(m+2)

Multiply the first terms in the two brackets.

Then multiply the two outer terms.

Followed by multiplying the inner terms.

Finally multiply the last terms

= (4m+3)(m+2)

4m² + 8m + 3m + 6

4m² + 11m + 6

So if you're asked to graph a function and its inverse, all you have to do is graph the function and then switch all x and y values in each point to graph the inverse. Just look at all those values switching places from the f(x) function to its inverse g(x) (and back again), reflected over the line y = x.

Answer:

6) 9 7) 8 8) 7 9) 9

Step-by-step explanation:

Answer: x = 15

Step-by-step explanation:

8x - 23 is half of 10x + 44

2 (8x - 23) = 10x + 44

16x - 46 = 10x + 44

Subtract 10x from both sides

6x - 46 = 44

Add 46 to both sides

6x = 90

Divide both sides by 6

x = 15

Answer:

x=14

Step-by-step explanation:

Hey There!

vertical angles are congruent so

5x-10=60

now we can solve for x

step 1 add 10 to each side

-10+10 cancels out

60+10=70

now we have

5x=70

step 2 divide each side by 5

70/5=14

we're left with x=14

Answer:

y = -x + 4

Step-by-step explanation:

Since the line is going from left to right downwards, it will have a negative slope.

The rate of change is -1/1 which can simply be written as -x.

The line crosses the y axis at 4, making it the y-intercept.

Answer:

Step-by-step explanation:

1. Write your formula

2. Plug it in

3. Solve

these steps will help you out with all of your surface area problems.

Like this

Since it is a diameter you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...

V = Bh                            (Pie is also known as 3.14)

your big (B) is (pie times r squared) Then you add your height.

so your formula will look like this...

V = pie times r squared...

the full formula will be...

V = (3.14) times (2.5 squared) times the height which in this case is (12)

everything together will be...

V = (3.14) (2.5^2) (12)

all you have to do is multiply all of that and you will get your answer.

The answer is...

V = 236 inches ^2                        (Just a tip, the ^ sign means to the power of)
