192π

Step-by-step explanation:

I've attached a screenshot I took from my calculator

(a) Basically, I did what the question asked by putting the numbers they gave into the formula they gave

(b) I did the same thing, except each number is squared

Answer:

S equal 28.

explanation: 180-90=90

90-58=32

32-4=28

Answer:

There are 6 angles!

Step-by-step explanation:

Answer:

2826  inches^2

Step-by-step explanation:

The general formula for the total surface area of a regular pyramid is

T.S.A.=12pl+B

Where p represents the perimeter of the base, l the slant height and B the area of the base.

The perimeter of the base is.  

p=2L+2W

P=2*10+2*9

P=20+18

P= 38  inches

The area of the base is.

B=10*9

B=90in^2

T.S.A.=12(38)(6)+90              

T.S.A=2736+90

T.S.A=2826  inches^2

Answer:

Step-by-step explanation:

To find the Scale factor we use this formula:

Scale factor / K  = Dimension of the new shape ÷ Dimension of the original shape

Substitute any 2 corresponding sides into the formula:

I took 1 and 4:

K = 1 / 4

K = 0.25

I'm not sure which form the question is so I will leave it here.

Answer:

4:1

Step-by-step explanation:

its ask from A to B

A is the bigger

if you divide a side from the bigger one

by the same side of the smaller one you'll get 4

6÷1.5 = 4

4.4÷1.1 = 4

4÷1 = 1

Answer:

21

Step-by-step explanation:

The coordinates of vertex A' are (-2, 1)

The coordinates of vertex B' are (-3, 3)

The coordinates of vertex C' are (-1, 3)

Answer:

Vertex A is (-2,1)

Vertex B is (-3,3)

Vertex C is (-1,3)

Step-by-step explanation: When finding Vertex, all you nees to do is find the ordered pairs. Ordered pairs are a set of numbers that are graphed at certain numbers on the x-axis and the y-axis. To find ordered pairs, start with the x-axis (the horizontal line) and find what number it is on. Then use the y-axis (the vertical line) and find what number the point is on.

Answer:

Hence, the unknown angle is 30°

Step-by-step explanation: Complementary Angle Calculator is a free online tool that displays the complementary angle for the given angle measure. BYJU’S online complementary angle calculator tool makes the calculation faster, and it displays the answer in a fraction of seconds.

How to Use the Complementary Angle Calculator?

The procedure to use the complementary angle calculator is as follows:

Step 1: Enter the angle in the input field

Step 2: Now click the button “Solve” to get the result

Step 3: Finally, the complementary angle for the given angle will be displayed in the output field

What is Meant by Complementary Angle?

In Maths, two angles are said to be complementary, when the angles add up to 90 degrees. The complementary angle need not be adjacent to each other, but its sum should be equal to 90 degrees. For example, 47° and 43° are complementary angles.

Example:

To find out another angle if one of the complementary angles is 60°

Solution:

We know that the sum of complementary angles is 90

Let the unknown angle be x

Thus,

60° + x = 90°

X = 90° – 60°

X = 30°

Hence, the unknown angle is 30°

Answer:

answer to 13 is 10

answer to 15 is 2,300?

Step-by-step explanation:

Answer:

3: Variable Equation =  If h is hours then 8h - 75

The answer is 8 hours.

My work is 42x8-75

4: Variable Equation = Let x be the amount spent on jeans, then

1) 45 + 10 + x = 90

x = 90 - 55 = 35

:

2) let n be the number of jeans he will purchase, then

35n < or = x

Note that x = 35, therefore

35n < or = 35

n < or = 1

Answer:

Michelle = 25

Alyssa = 13

Amanda = 9

Step-by-step explanation:

         We will set up equations for this problem to help us solve this problem mathematically. Let x be Alyssa, y be Michelle, and z be Amanda.

    [] Alyssa is 12 years younger than Michelle.

x = y - 12

    [] Michelle 25 ()is 7 years older than twice Amanda's age.

y = (2x) + 7

    [] The sum of all three ages is 47.

x + y + z = 47

    You gave that y = 25,

Michelle is 25.

    Since we know that Alyssa is 12 years younger than Michelle, we can solve for Alyssa.

x = 25 - 12

x = 13

Alyssa is 13.

    Lastly, the sum of all three ages is 47.

x + y + z = 47

13 + 25 + z = 47

z = 9

Amanda is 9.

Answer:

The area of a trench is 5.5 m² .

Step-by-step explanation:

Formula

Area of a rectangle = Length × Width

As given

Tanya has a garden with a trench around it.

i.e

Put in the above formula

                            = 5 m²

As given

i.e

                                                 = 10.5 m²

Area of the trench = Area of garden with trench - Area of garden

Put the value in the above

Area of the trench = 10.5 m² - 5 m²

                              = 5.5 m ²

Therefore the area of a trench is 5.5 m² .

Answer:

It should be roughly 5.36 cm³

-------------------------------------------------------------------------------------------------------------

Set the value for volume.

[tex]V = a^3[/tex]

a means the missing edge, here.

[tex]a^3 = 5.36^3\\\\5.36^3 = 5.36 * 5.36 * 5.36 = 153.99~cm^3[/tex]

That said, the closest you can get is 5.36

Answer:

(4/3)×3×4^3=256

Step by Step Explanation:

First, replace all the letters and signs with number, which will look like (4/3)×3×4^3. The r in the equation means radius and radius is half of the diameter (which is the 8), so that means the r is 4. Then, on your calculator, type in (4/3)×3. you should get 4. then take the 4 and muktuplmultiple

Answer: [tex]V=47,721.9in^3[/tex]

Step-by-step explanation:

The volume of a hemisphere would be 1/2 of the volume of a sphere. The volume of a sphere is defined to be:

[tex]V=\frac{4}{3} \pi r^3[/tex]

Therefore the volume of a hemisphere would be:

[tex]V=\frac{1}{2}( \frac{4}{3} \pi r^3)=\frac{2}{3} \pi r^3[/tex]

Plug everything in:

[tex]V=\frac{2}{3} \pi r^3=\frac{2}{3} \pi (28.35)^3=47,721.9in^3[/tex]
