Answer:

  25.12 cm²

Step-by-step explanation:

The area of a circle is given by the formula ...

  A = πr²

where r is the radius. Here, the diameter is given as 8 cm, so the radius will be half that, or 4 cm. The area is then ...

  A = 3.14(4 cm)² = 50.24 cm²

The green shaded part is 1/2 a circle, so is half this area:

  shaded area = 25.12 cm²

A line is found to be a one dimensional figure, which has length but no width. The another name for the line n is line. The two points which lie on the same line are called collinear points. The correct option is D.

A straight set of points which can extend in opposite directions can be defined as the line. It has no ends in both directions, no thickness and it is one dimensional. It is determined by two points in a two dimensional plane.

In geometry, there are different types of lines like horizontal and vertical lines, parallel and perpendicular lines. The lines play an important role in the construction of different types of polygons.

A square is made by four lines of the same lengths, whereas a triangle is made by joining three lines end to end.

Thus the correct option is D.

Answer:

1

Step-by-step explanation:

13(2x-1)-3(9x-8) = 10

or, 26x-13-(27x-24) = 10

or, 26x-13-27x+21 = 10

or, 11 - x = 10

or, 11 - 10 = x

therefore, x = 1

Answer:

The answer would be 8.7

Step-by-step explanation:

First, you would start with the parentheses. So add 32+8.3 to get 40.3.

The equation will look like this: 49-40.3

The final step would be subtraction.

49-40.3= 8.7

You will get 8.7 as your answer!

The given statement is false.

We have the following statement -

Square root of 8 is between 7 and 9.

We have to determine if it is true or false.

Square root of a number is a value, which on multiplication by itself gives the original number.

According to the question -

A = [tex]\sqrt{8}[/tex] = 2.82

Clearly, it is not between 7 and 9.

Therefore, the statement is false.

Step-by-step explanation:

Use the operations from the sentence into the equation and solve.

Answer:

2(3x+6), 6(x+2), and 3(2x+4)

Step-by-step explanation:

Answer:

n=5

x= 23

p= 4

Step-by-step explanation:

What this wants us to do is find the value of the variable first, then find the measurement of the degrees.

So, for the first equation we need to make an equation.

Since the angles are vertical angles, that means they equal each other.

The equation would be.. 8n=9n-5.

Step 1- Move variable to the left hand side and change its sign

8n-9n= -5

Step 2- Collect like terms

-n= -5

Step 3- Change signs on both sides of the equation

n=5

So, now that we know what the variable is, substitute it into the equations.

8(5)= 40    9(5)-5= 40

For the second equation, the angles equal 180 degrees.

So, that would give us the equation.. 6x+19+x= 180.

Step 1- Add the common variables

(6x+x)+19= 180

7x+19= 180

Step 2- Subtract 19 from both sides.

7x+19= 180

   -19    -19

7x= 161

Step 3- Divide both sides by 7

7x= 161

7     7

x= 23

So, now that we know what the variable is, substitute it into the equations.

6(23)+19= 157

157+23= 180

Finally for the last equation, they are vertical angles, so they equal each other.

So, the equation would be 5p+28= 12p.

Step 1- Move the variable to on side.

5p+28= 12p

-5p         -5p

28= 12-5p

Step 2- Subtract the variables

28= 7p

Step 3- Divide by 7 to both sides.

28= 7p

7     7

p= 4

So, now that we know what the variable is, substitute it into the equations.

5(4)+28= 48

12(4)= 48
