The volume is a measurement of three-dimensional space that is utilized.

Let r be the radius and h be the height of the cylinder and cone. Then the volume of the cylinder will be given as,

Volume of A = π r²h cubic units                       ...1

And the volume of the cone will be given as,

Volume of B = (1/3) × r²h cubic units       ...2

From equations 1 and 2

Volume of B = 3 x volume of A

The amount of water in Glass B to equal to 3 times of the amount water in Glass A

Answer:

the answer to a is -27 the answer to d is 28 the answer to gis 15

Answer:

Assuming the area is made up of a square and a semicircle.

Perimeter

The side length of the square = 18 ft

We can see 3 full side lengths plus one side length from which we need to subtract 12 ft (see attached diagram).

⇒ perimeter of the square = (3 x 18) + (18 - 12)

                                                          = 54 + 6

                                                          = 60 ft

Circumference of a circle = [tex]\pi[/tex]d (where d is the diameter)

⇒ arc length of the semicircle = 1/2 circumference

                                                  = 1/2 · [tex]\pi[/tex] · 12

                                                  = 6[tex]\pi[/tex] ft

Total perimeter = 60 + 6[tex]\pi[/tex] = 78.8 ft (nearest tenth)

Area

Area of a square = s² (where s is the side length)

⇒ area of square = 18²

                             = 324 ft²

Diameter = 2r  ⇒  r = 1/2 diameter

Area of a circle = [tex]\pi[/tex]r²  (where r is the radius)

⇒ area of the semicircle = 1/2 · [tex]\pi[/tex] · 6²

                                         = 18[tex]\pi[/tex] ft²

Total area = 324 + 18[tex]\pi[/tex] = 380.5 ft² (nearest tenth)

Answer:

The formula that is used to determine the volume of the cylinder in terms of pi is V = πr2h cubic units where, "V", "r" and "h" are the volume, radius, and height of the cylinder. This formula of volume of the cylinder also shows its dependence on the radius and height of the cylinder.

Answer:

miles to travel directly south = 54 miles (to the nearest mile)

extra miles = 68 miles (nearest mile)

Step-by-step explanation:

We need to find the height of the right triangle in the diagram.

To do this, use the sine trig ratio.

[tex]\sin(x)=\sf\dfrac{O}{H}[/tex]

where:

Given:

[tex]x[/tex] = 27°

O = height (h)

H = 120 miles

Substituting the given values into the formula:

[tex]\implies \sin(27^{\circ})=\sf\dfrac{h}{120}[/tex]

[tex]\implies \sf h=120 \sin(27^{\circ})[/tex]

[tex]\implies \sf h=54.47885997...[/tex]

Therefore, the shipmate will have to travel 54 miles (to the nearest mile) directly south.

To find the number of extra miles have been traveled, we first need to find the base length of the right triangle.

To do this, use the cos trig ratio.

[tex]\cos(x)=\sf\dfrac{A}{H}[/tex]

where:

Given:

Substituting the given values into the formula:

[tex]\implies \cos(27^{\circ})=\sf\dfrac{b}{120}[/tex]

[tex]\implies \sf b=120 \cos(27^{\circ})[/tex]

[tex]\sf \implies b=106.9207829...[/tex]

Therefore, the base of the right triangle is 106.9207829... miles

To find the extra miles, sum the hypotenuse and the height of the triangle, then subtract the base.

Extra miles = (120 + 54.47885997... ) - 106.9207829...

                  = 67.55807707...

                  = 68 miles (nearest mile)

Total distance travelled =120+54.5=174.5ft

Extra distance:-

The perimeter of the semicircular region is the circumference of the semicircle plus the diameter

                 d: diameter length

                  r: radius length

6. [tex]Perimeter=\frac{1}{2}\pi d + d= \frac{1}{2} \pi *18+18=9\pi +18 = 46.26cm[/tex]

7. [tex]Perimeter =\frac{1}{2}\pi d+d= \frac{1}{2} \pi *20+20 = 31.4+20=51.4 in[/tex]

Answer:

220.5 sq feet

Step-by-step explanation:

Given : Bev has to cut her grandma's grass this weekend

Six-sided polygon that includes two isosceles right triangles, one with height and base of 15 feet, the other height and base of 4 feet, and one rectangle measuring 25 feet by 4 feet.

To Find : Area of Polygon

Solution:

Area of triangle = (1/2) bh

= (1/2) * 15 * 15

= 112.5   sq feet

= (1/2) * 4 * 4

=  8   sq feet

Area of rectangle = 25 x 4 = 100   sq feet

Total area =112.5 +  8  + 100

= 220.5 sq feet

Area of Polygon = 220.5 sq feet

Answer:

398 ft²

Step-by-step explanation:

Assuming you have correctly described the total area in terms of non-overlapping triangles and a rectangle, you can put the dimensions into the appropriate area formula and add up the pieces.

Triangle area = 1/2·bh

Rectangle area = bh

___

So, the first triangle has an area of ...

1/2·(20 ft)(20 ft) = 200 ft²

The second triangle has an area of ...

1/2·(6 ft)(6 ft) = 18 ft²

The rectangle has an area of ...

(30 ft)(6 ft) = 180 ft²

And the area total is ...

200 ft² +18 ft² +180 ft² = 398 ft²

How to calculate tax and earning

Given the following paramiters

Total amount earned by the student = $15000

Assume we have the following parameters

Earning paid off in taxes = $1500

Amount spent on living expenses = $3000

Amount she will have left = 15000 - (1500 + 3000)

Amount she will have left = 15,000 - 4500

Amount she will have left = 10,500

Hence the amount she will have left is $10,500

Answer:

$7,500

Step-by-step explanation:

First, find the amount he pays in taxes:

$15,000 x 0.1 = $1,500

Next, find the amount he pays in living expenses:

$15,000 x 0.4 = $6,000

Add the two amounts together:

$1,500 + $6,000 = $7,500

Subtract the combined amount from the original amount to find how much the student saved:

$15,000 - $7,500 = $7,500

Therefore, the college student saves $7,500.

i used a calculator

Answer:

A and infinite solutions

Step-by-step explanation:

4/5x - 8 = 4(1/5x - 2)

4(1/5x - 2)

4/1 x 1/5x = 4/5x

4 x (-2) = -8

Put them together and you get:

4/5x - 8 AND

4/5x - 8 = 4/5x - 8

IF 2 SIDES OF AN EQUATION ARE THE SAME THEN THE ANSWERS ARE INFINITE

YOU CAN TURN THE EQUATION INTO JUST (x = x)

Answer

B and One Solution

Step-by-step explanation:

4/5x - 8 = -(4/5x + 2)

-(4/5x + 2) = -4/5x - 2

ADD 4/5x TO THE BOTH SIDES

8/5x - 8 = -2

ADD 8 TO BOTH SIDES

8/5x = 6

DIVIDE BOTH SIDES BY 8/5 OR 1.6

x = 3.75

You can get through the last one. Reply if you need me to

Answer:

[tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex]

Step-by-step explanation:

y= mx +c, where m is the slope and c is the y-intercept.

We need to find the value of m and c, which can be done by using the slope formula and by substituting a pair of coordinates respectively. Find m first before finding the value of c.

[tex]\boxed{ slope = \frac{y _{1} - y_2 }{x_1 - x_2} }[/tex]

[tex]slope = \frac{7 - ( - 4)}{5 - ( - 8)} [/tex]

[tex]slope = \frac{7 + 4}{5 + 8} [/tex]

[tex]slope = \frac{11}{13} [/tex]

Substitute the value of m into the equation:

[tex]y = \frac{11}{13} x + c[/tex]

Substitute a pair of coordinates:

When x= 5, y= 7,

[tex]7 = \frac{11}{13} (5) + c[/tex]

[tex]c = 7 - \frac{55}{13} [/tex]

[tex]c = \frac{91}{13} - \frac{55}{13} [/tex]

[tex]c = \frac{36}{13} [/tex]

[tex]c = 2 \frac{10}{13} [/tex]

Thus, the equation of the line is [tex]y = \frac{11}{13} x + 2 \frac{10}{13} [/tex].
