O diameter.

Answer:

86 cm²

Step-by-step explanation:

1) Calculate the area of the square

[tex]A=lw\\A=20*20\\A=400[/tex]

Therefore, the area of the square is 400 cm².

2) Calculate the area of the circle

[tex]A=\pi r^2\\[/tex]

[tex]\pi[/tex] we can substitute with 3.14. To find the radius, we divide the diameter of the circle by 2. 20 cm is the diameter of the circle, so therefore, its radius is 10 cm.

[tex]A=3.14*10^2\\A=3.14*100\\A=314[/tex]

Therefore, the area of the circle is 314 cm².

3) Subtract the area of the circle from the area of the square

[tex]A=400-314\\A=86[/tex]

Therefore, the area of the shaded region is 86 cm².

I hope this helps!

Step-by-step explanation:

Given,

One side of the square = 20 cm

Therefore, Area of the square = side × side

= 20 cm × 20 cm

[tex] \: \: \: \: \: \: \: \: = 400 {cm}^{2} [/tex]

Also, known that

One side of the square = Diameter of the circle = 20 cm

So, radius of the circle = 20/2 cm = 10 cm

Therefore, area of the square

[tex] \: \: \: \: \: \ \: \: \: \: = \pi{r}^{2} [/tex]

[tex] = 3.14 \times {(10cm)}^{2} [/tex]

[tex] = 3.14 \times 100 {cm}^{2} [/tex]

[tex] = 314 {cm}^{2} [/tex]

Hence, area of the shaded region is

= Area of the square. - Area of the circle

[tex] = 400 {cm}^{2} - 314 {cm}^{2} [/tex]

[tex] = 86 {cm}^{2} (ans)[/tex]

Answer:

a = 45°

Step-by-step explanation:

2a + a + a = 180°

4a = 180°

4a ÷ 4 = 180° ÷ 4

a = 45°

Step-by-step explanation:

4x2 = 8

3 + 3 = 6

so 8x to the 6th

The 6 faces of a cube have equal are.

Each face has are of 5*5=25 because they are all squares.

Now we just multiply by 6

25*6=150 centimeters cubed.

Done!

Step-by-step explanation:

step 1. a cube had 6 sides

step 2. each side is a square

step 3. the area of each side is 5x5 = 25cm^2

step 4. the surface area of the cube is 25x6 = 150cm^2.

Answer:

f(-2)=27

Step-by-step explanation:

Plug in -2 into x

f(-2)=2(-2)^2-8(-2)+3

f(-2)=8+16+3

f(-2)=27

▪︎Side 15 cm, 18 cm and x cm form a right angle triangle.

We know that :

[tex] =\tt {hypotenuse}^{2} = {leg}^{2} + {leg}^{2} [/tex]

Which means :

[tex] =\tt {15}^{2} + {x}^{2} = {18}^{2} [/tex]

[tex] =\tt 225 + {x}^{2} = 324[/tex]

[tex] =\tt {x}^{2} = 324 - 225[/tex]

[tex] = \tt {x}^{2} = 99[/tex]

[tex]\color{plum} =\tt x = 9.9 \: cm[/tex]

Thus, x (radius) = 9.9 cm

We know that :

[tex]\color{hotpink}\tt \: Surface \: area \: of \: cone \color{plum}=\pi r(r + \sqrt{ {h}^{2} + {r}^{2} } [/tex]

Then, the surface area of this cone :

[tex] = \tt3.14 \times 9.9 \times( 9.9 + \sqrt{ {15}^{2} + {9.9}^{2} } )[/tex]

[tex] =\tt 3.14 \times 9.9 \times( 9.9 + \sqrt{323.01} )[/tex]

[tex] =\tt 3.14 \times 9.9 \times (9.9 + 18)[/tex]

[tex] =\tt 3.14 \times 9.9 \times 27.9[/tex]

[tex] = \tt31.09 \times 27.9[/tex]

[tex]\color{plum} =\tt\bold{ 867.4 \: cm}[/tex]

Therefore, the surface area of this cone = 867.4 cm

Answer:

1260cm^2

Step-by-step explanation:

BC : CD

12 : 24

12 + 24 = 36

h²- a² = b²

37²-12²  

1369 - 144 = 1225

√1225 = 35

36 x 35 = 1260cm²

Answer:

9a + 5b + 4 is written as a sum of three terms, 4 is a constant, 9a is a coefficient.

Step-by-step explanation:

A coefficient is the number before a letter. In some cases it would be the number you either multiply or divide by another number. A constant is a single number that either isn't changed or is added or subtracted by another coefficient (alone) . A term is just a mathematical expression used in math. It is either just a normal equation or a big expression like this one. You also cant add or subtract 9a by 5b or 4 because in order to to do that 5b or 4 has to have an "a" at the end~example- instead of 5b it would have to be 5a to subtract or add or do whatever . (has to be the same)

Given:

The table of values.

To find:

The equation in slope intercept form.

Solution:

From the given table it is clear that the line passes through the points (5,17), (8,41) and (12,73).

Consider any two points from the table, i.e., (5,17) and (8,41). So, the equation of line is

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-17=\dfrac{41-17}{8-5}(x-5)[/tex]

[tex]y-17=\dfrac{24}{3}(x-5)[/tex]

[tex]y-17=8(x-5)[/tex]

[tex]y=8x-40+17[/tex]

[tex]y=8x-23[/tex]

Therefore, the equation of line in slope intercept form is [tex]y=8x-23[/tex].

Answer:

2.8

Step-by-step explanation:

You need to keep these: 2.8

You will need to look at the second decimal: 2.844

Since it is under 5, you don’t need to increase 8 any further. If it was 5 or greater, you would have to change the 8 up to a 9.

Answer:

Given :  A toy car is placed on the floor. Its movement details are given

To find : Distance covered by Car & graph to be plotted

Solution:

Start from rest

u = 0  at  t = 0

Constant acceleration for 3 sec reaching velocity 4 m/s

V = U +at

=> 4 = 0 +  a(3)

=>a = 4/3  m/s²

Distance here  S = ut + (1/2)at²

S = 0 + (1/2)(4/3)3²

=> S = 6 m

deceleration of 0.5 m/s² for 4 sec

=> v = 4  - (0.5)4

=> v = 2 m/s

Distance here   =  4(4)  - (1/2) (0.5)4²

= 16 - 4

= 12 m

Total Distance = 6 + 12 = 18 m

Total Distance traveled by toy Car = 18 m

Answer:

$ 4,500.00

Step-by-step explanation:

I = $ 4,500.00

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 9%/100 = 0.09 per year,

then, solving our equation

I = 10000 × 0.09 × 5 = 4500

I = $ 4,500.00

The simple interest accumulated

on a principal of $ 10,000.00

at a rate of 9% per year

for 5 years is $ 4,500.00.
