Answer:

The formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04

Step-by-step explanation:

Answer:

Volume - 452.16 cm

Step-by-step explanation:

First we need to find the area of the circle.

Area of a circle - (3.14)r^2

Insert the radius in the formula -

(3.14) (4)^2

3.14 x 16

50.24 is the area of the circle

Now, we have to multiply this value by the height of the cylinder in order to find the volume.

50.24 x 9 = 452.16 cm

Answer:

96×pi ft³

Step-by-step explanation:

by the way, it is totally easy to search for formulas on the internet.

the volume of a cone is

Vc = pi×r²×height/3

we have been given the slant height (10 ft) and the lateral "wall" area of the cone (60×pi ft²).

this wall area is

Aw = pi×r×slant height

60×pi = pi×r×10

60 = r×10

6 = r

so, now we know r fuer the volume formula, and we need the height of the cone (the inner one).

we use Pythagoras

10² = r² + height²

100 = 36 + height²

height² = 64

height = 8 ft

so, now we use the main formula for the volume

Vc = pi×r²×height/3 = pi×6²×8/3 = pi×36×8/3 = pi×12×8 =

= 96×pi ft³

cubic feet ! it is a volume !

Answer:

the answer is 5/33

Step-by-step explanation:

Total marbles = 5 blue + 4 red + 3 yellow = 12

Two marbles are selected, first is blue which gives us :

5/12 --eq 1

Then red marble is selected ( note: one marble is already drawn and not replaced so we have a total of 11 marbles )

The probability of red gave us :

4/11 --eq 2

Now we multiply eq 1 and 2

5/12 x 4/11 = 5/33

Answer:

Step-by-step explanation:

take x degree as reference angle

using sin rule

sin x=opposite/hypotenuse

sin x=9/18

sinx=0.50

x=sin 30

x=30 degree

Answer:

I'll setup the problem, you do the calculation

Step-by-step explanation:

given the area of a square, you take the square and that is the side of the square

[tex] \sqrt{9 {q}^{4} {r}^{8} {s}^{6} } [/tex]

the square root of a number that is raised to a power is found by dividing the power by 2

example

[tex] \sqrt{ {x}^{6} } = {x}^{3} [/tex]

do that for each term and you have you answer

(-7x + 12) (x + 1)

Answer:

9

Step-by-step explanation:

Because all other answers round down

Answer:

The missing digit is 9

Step-by-step explanation:

For this question, we would look at rounding rules. Given that the first 3 numbers after the decimal are 383, if we want the secon 3 to round up to a 4, then the 4th number after the decimal would have to be greater than or equal to 5. The only option that matches this is 9. Hope this helps!

The answer is option C. 13/15

Step-by-step explanation:

Answer:

y=-4x+4

Step-by-step explanation:

y-y1=m(x-x1)

y-(-4)=-4(x-2)

y+4=-4(x-2)

y=-4x+8-4

y=-4x+4

A slope of a line is the change in y coordinate with respect to the change in x coordinate. The equation of the line in slope intercept form which is passing through (2,-4) is  -4x +7.

A slope of a line is the change in y coordinate with respect to the change in x coordinate. The equation of a line in slope intercept form is given by

y = mx + c.

Given the slope of the line, m=-4. Also, the point through which the line is passing,

(x₁ ,y₁) =(2,-4)

Since the equation of the line in the slope-intercept form of the line is given by

y = mx +c

Since, the above line is passing through (2, -4) and the slope is -4.

Therefore,-4 = -4(2) + c⇒ -4 = -8 + c⇒ -1 +8 = c⇒ c = 7

Substitute the value of m and c in the equation

y = mx + c

⇒ y = mx + c

⇒ y = -4x +7

Therefore, the equation of line in slope intercept form which is passing through (2, -4) is y = -4x +7.

Answer:

[tex]a_{n}[/tex] = 5n + 4

Step-by-step explanation:

There is a common difference between the consecutive terms of y

29 - 24 = 24 - 19 = 19 - 14 = 14 - 9 = 5

This indicates the sequence is arithmetic with explicit formula

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 9 and d = 5 , then

[tex]a_{n}[/tex] = 9 + 5(n - 1) = 9 + 5n - 5 = 5n + 4

Answer:

Part A. Answer: The company will be successful selling 23 shirts.

Part B. Answer: The company will not be successful selling 10 shirts.

Part C. Answer: 13 shirts

Step-by-step explanation:

initial cost: $50

cost per shirt: $3

sale price per shirt: $7

number of shirts: x

The cost, y, of x shirts is

y = 3x + 50

Part A.

cost of 23 shirts

y = 3(23) + 50

y = 119

revenue from selling 23 shirts:

23 * $7 = $161

It costs $119 to make 23 shirts. They are sold for $161.

Part A. Answer: The company will be successful selling 23 shirts.

Part B.

cost of 10 shirts

y = 3(10) + 50

y = 80

revenue from selling 10 shirts:

10 * $7 = $70

It costs $80 to make 10 shirts. They are sold for $70.

Part B. Answer: The company will not be successful selling 10 shirts.

Part C.

To break even, the cost and the revenue must be equal.

Cost of x shirts: 3x + 50

Revenue from selling x shirts: 7x

7x = 3x + 50

4x = 50

x = 12.5

The break even point is 12.5 shirts. Since the number of shirts sold must be a whole number, the break even number is 13.

Part C. Answer: 13 shirts.

Step-by-step explanation:

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex] where h and k are the center of the circle and r is the radius. Our center is located at (0, 1), so h = 0 and k = 1. Going from the center straight up of down we have to move 2 units to get to a point on the outside of the circle, so r = 2. Filling in our equation:

[tex](x-0)^2+(y-1)^2=2^2[/tex] which simplifies a bit to

[tex]x^2+(y-1)^2=4[/tex]

[tex]slope = \frac{1}{2} [/tex]

Answer:

1 = 117 ( vertically opposite angles are equal )

2 = 117 ( corresponding angles are always equal )

Step-by-step explanation:

Answer:

angle one=122 because it is using the alternate interior angle theorem

angle 2=58 because it is using the consecutive interior angle theorem

hope this helps

have a good day :)

Step-by-step explanation:

remember consecutive=same sine 122 is on the same side of angle 2 just substract 180-122=58

since 122 is on the opposite side of angle 1 it's going to be alternate something so since it's on the inside its going to be alternate interior angle

Answer:

9 :  7, or 9/16 to 7/16

Step-by-step explanation:

We know that there are 9 blue hats.

We know there are 7 red hats.

This is a 9 : 7 ratio.

In fraction form, we must find the total ratio, use that as the denominator, then take the seperate amounts, such as bluei adn red hats, and use that as the numerator:

9+7=denominator

denominator = 16

Blue hats = 9

Ratio of red = 9/16

Red hats = 7

Ratio of red = 7/16
