Answer:

1. V≈1244.07

2. V≈54286.72

3.V≈23816.41

4. V≈254.47

5. V≈4247.43

6. V≈21714.69

7. V≈4712.39

Step-by-step explanation:

use the formula V=πr^2h

The volume of the given cylinders is 1. V≈1244.07 2. V≈54286.72 3. V≈23816.41 4. V≈254.47 5. V≈4247.43 6. V≈21714.69 7. V≈4712.39.

The volume of the cylinder is the product of the height, pie, and square of the radius.

The volume of the cylinder = [tex]\pi r^{2} h[/tex]

A.

a) The height of the cylinder is given as 11 in and the radius is 6 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 6^2 x 11

                                                    = 1244.07cubics in

b)  The height of the cylinder is given as 30 in and the radius is 24 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 24^2 x 30

                                                    = 54286.72 cubics in

c) The height of the cylinder is given as 21 in.

The radius of the base of the cylinder is given as 19 in.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 19^2 x 21

                                                    = 23816.41 cubics in

B.

d) The height of the cylinder is 9ft the radius is 3 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 3^2 x 9

                                                    = 254.47 cubics ft

e) The height of the cylinder is 8 ft the radius is 13 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 13^2 x 8

                                                    = 4247.43 cubics ft

f) The height of the cylinder is 27 ft the radius is 16 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 16^2 x 27

                                                    = 21714.69 cubics ft

g) The height of the cylinder is 15 ft the radius is 10 ft.

So, The volume of the cylinder = [tex]\pi r^{2} h[/tex]

                                                    = 3.14 x 10^2 x 15

                                                    = 4712.39 cubics ft

Answer:

(x+2)(3x+4)

Step-by-step explanation:

I think that the answer is (3x + 4)

(x + 2)

Answer:

x = 32

Step-by-step explanation:

24 x 4 = 3x

24 x 4 = 96

96 / 3 = 32

x = 32

Answer:

x = 32

Step-by-step explanation:

You want to find x.

First, simplify and combine like terms. Using PEMDAS, do the parenthesis first.

(3 x 8) x 4 = 3x

24 x 4 = 3x

96 = 3x

Now, divide each side by 3 to isolate x.

x = 32

Answer:

- 978.6 gallons per hour

Step-by-step explanation:

Given that :

Change in gasoline (gallon) : 58,432.4 gal to 56,475.2 gal

Time during which change occurred : 2:00 pm to 4:00 pm

Average change per hour : [Change in gallon of gasoline / time interval (hour)]

Change in gallon of gasoline = (56,475.2 - 58,432.4) = - 1957.2 gallons

Time interval = 4:00 pm - 2:00 pm = 2 hours

Hence, Average change per hour :

-1957.2 / 2

= - 978.6 gallons per hour

Divide the numbers on the scale drawing by 3. 75 divided by 3 equals 25, 51 divided by 3 equals 17, 30 divided by 3 equals 10, and 72 divided by 3 equals 24. Letter B has all of those answers.

Answer:

18

Step-by-step explanation:

the ratio of blue eyed students to non-blue eyed students is 7 to 12,

Total ratio = 7+12=19

Total student= 50 students

Ratio of blue eyes student= 7/19 ×50

=18.4

Hence, there are approximately 18 students with blue eyes.

Answer:

16 1/15

Step-by-step explanation:

Add the whole numbers.  7+8=15

Now, combine the fractions 2/3 and 2/5. To do so, you need a common denominator. The LCD between 3 and 5 is 15.

Whatever you do to one side you must do to the other.

(5/5) 2/3+ 2/5 (3/3)

10/15+6/15=16/15

15+16/15

16/15 is an improper fraction, so convert this fraction to a mixed number.

16/15= 1 1/15

Finally, add the two together. 15+ 1 1/15=

Answer:

Q = P - n(x/100)

Step-by-step explanation:

P is the total number of lace edging, n is the number of times the length x is cut from P, and Q is the remnant of the reduction.

So the number of x length is subtracted from P and must be converted to meters (since it is in centimeters) to get Q. That is;

Q = P - n(x/100)

x = 80

Step-by-step explanation:

All angles in a triangle add up to 180 degrees.

First, find the angle J:

60+40 = 100, J = 80 because 100+80= 180 degrees.

Now, the two angles on either side of J should also equal 180 degrees. We know that the inner angle is equal to 80 degrees. Thus, the outside angle must equal 100.

x + 20 = 100

x = 80 degrees.

Answer:

x = 48°

Step-by-step explanation:

In the given triangle XYZ,

Sides XY and XZ are congruent.

Therefore, both the sides will be equal in measure.

By the definition of isosceles triangle,

"Opposite angles of the equal sides are equal in measure"

m∠Y = m∠Z = x°

m∠X = 84° [Given]

By the triangle sum theorem,

m∠X + m∠Y + m∠Z = 180°

84° + x° + x° = 180°

2x = 180 - 84

x = 48°

Therefore, measure of x = 48° will be the answer.
