Answer:

1815 pi cm^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h

We know the diameter =22

so the radius is d/2  = 22/2 =11

V = pi (11)^2 (15)

V = pi1815

V = 1815 pi cm^3

Answer:

DE = 11.25 units

Step-by-step explanation:

The image of the quadilateral BCED and the extensions of BD and CE to move past B and C to meet at A is presented in the attached file to this answer.

Let the angle at A be θ

Let the length of DE be x

ABC forms a triangle which van allow θ to be obtained using cosine rule.

BC² = AB² + AC² - (2×AB×AC×cos θ)

BC = 9

AB = 24

AC = 28

9² = 24² + 28² - (2×24×28×cos θ)

-1279 = -1344 cos θ

Cos θ = (1279/1344) = 0.9516

θ = 17.89°

Note that ADE also forms a triangle and we can also use cosine rule to obtain the required side DE

DE² = AD² + AE² - (2×AD×AE×cos θ)

DE = ?

AD = AB + BD = 24 + 11 = 35

AE = AC + CE = 28 + 2 = 30

θ = 17.89°

DE² = 35² + 30² - (2×35×30×cos 17.89°)

DE² = 126.54

DE = √126.54 = 11.25

Hope this Helps!!!

The value of DE in the quadrilateral is 11.25 units.

From the information given, the cosine rule can be used. This will be:

BC² = AB² + AC² - (2 × AB ×AC × cos)

Therefore,

9² = 24² + 28² - (2 × 24 × 28 × cos)

cos = 17.89°

Therefore, the value of DE will be calculated thus:

DE² = 35² + 30² - (2 × 35 × 30 × cos 17.89)

DE = ✓126.54

DE = 11.25

In conclusion, the value of DE is 11.25 units.

Area of Shaded Region ≈ 141.37 cm^2

Step-by-step explanation:

Given radius of 9 cm for the outer circle;

πr^2, ⇒ Substitute value of radius,

π * ( 9 )^2 ⇒ Square 9, keeping value in terms of π,

Area of Outer Circle; 81π

Provided a radius of 6 cm for the inner circle;

πr^2, ⇒ Substitute value of radius,

π * ( 6 )^2 ⇒ Square 6, keeping value in terms of π,

Area of Inner Circle; 36π

Take the shaded region to be the value of the inner circle ( area ) subtracted from the area of the outer circle;

Area of Shaded Region ⇒

81π - 36π =

45π =

Area of Shaded Region ≈ 141.37 cm^2

Answer:

6√2

Step-by-step explanation:

This is a right triangle. The legs of a right triangle are the sides that make up the right angle, and the hypotenuse is the side opposite to the right angle. To find x, we will use the Pythagorean Theorem. This states that a² + b² = c², where a and b are the legs and c is the hypotenuse. Since we know that the legs are both x and the hypotenuse is 12, we can plug these values into our equation to get  x² + x² = 12².

2x²=144 → x² = 72 → x = √72, which simplifies to x = 6√2. Hope this made sense and helps!

Answer: >,<

Step-by-step explanation:

18 qt = 4.5 gallons which is not greater than 5 gallons

4.5km = 4,500 m is not greater than 5,000 m

Answer:

1st: 5 gal > 18 qt

2nd: 4.5 km < 5,000 m

Step-by-step explanation:

1 gallon is equal to 4 quarts

Going by this logic, 5 gallons should be 20 quarts. Since it says 18, 5 gallons is more than it. So the answer is '>'.

1 kilometer is the same as 1000 meters

4.5 kilometers * 1000 = 4,500 meters

5000 meters / 1000 = 5km

So the answer should be '<' since 5,000m is greater than 4.5km.

Step-by-step explanation:

-15 = 2x + 1

Subtract 1 from each side

-15-1 = 2x + 1-1

-16 = 2x

Divide each side by 2

-16/2 = 2x/2

-8 =x

Check

-15 = 2(-8) + 1

-15 = -16+1

-15 = -15

Answer:

-8

Step-by-step explanation:

subtract 2x to move it to the left side

-2x-15=1

add 15 to move it to the right side then add 1 to 15 since it would be 15 plus 1

-2x=16

divide by -2 to get x by its self

-2x=16/2x

Answer:

155

Step-by-step explanation:

The measure of <1 is 25.

The fundamental characteristics listed below make it simple to recognize parallel lines.

Given:

The streets represented by lines V and W are parallel.

We need to determine the measure of ∠1.

As, Corresponding angles are those in the matching corners formed when a transversal line crosses two parallel lines.

Additionally, the size of the corresponding angles is consistently the same.

So, From the figure, the ∠1 and the other angle in the parallel line V with the measure of angle 155° are corresponding angles.

Thus, the measure of ∠1 is 155°

The Last Equation

Step-by-step explanation:

[tex]2(x+3)=32[/tex] is the same thing as [tex]2x+6=32[/tex].

Why? Because if you apply the distributive property...

[tex]2(x+3)=32\\2 * x =2x\\2*3 = 6\\\boxed {2x+6=32}[/tex]

You get what was mentioned in the question!

So, 2(x+3)=32 should have the same solution as 2x + 6 =32.

Brainilest Appreciated.

Answer:

The bottom choice, 2(x + 3) = 32

Step-by-step explanation:

2x + 6 = 32

Subtract 6 from both sides of the equation

2x = 26

x = 13

Substitute the new value for x into all of the possible equations

1) 2x = 38,       2)  x - 3 = 16        3)  x + 6 = 16       4)   2(x - 3) = 16        

13 * 2 = 38           13 - 3 = 16           13 + 6 = 16              2x - 6 = 16

26 = 38                 10 = 16                  19 = 16                 13(2) - 6 = 16

False                     False                    False                   26 - 6 = 16

                                                                                           20 = 16

                                                                                             False

5)  2(x + 3) = 32

     2x + 6 = 32

    2(13) + 6 = 32        

      26 + 6 = 32

          32 = 32

             True

              The last answer choice, (the 5th one down) is correct
