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

Where, r = Radius

[tex] \frac{\pi {d}^{2} }{4} [/tex]

d = diameter

[tex]\pi = 3.14[/tex]

1.)

r = 3cm

Area = 3.14 × 3² = 28.26 cm²

2.)

r = 4 in

Area = 3.14 × 4² = 50.24 in²

3.)

r = 10 m

Area = 3.14 × 10² = 314 m²

4.)

r = 2cm

Area = 3.14 × 2² = 12.56 cm²

5.)

r = 9 ft

Area = 3.14 × 9² = 254.34 ft²

6.)

r = 1.2 km

Area = 3.14 × 1.2² = 4.52 km²

7.)

r = 50 in

Area = 3.14 × 50² = 7850 in²

8.)

r = 11 m

Area = 3.14 × 11² = 379.94 m²

9.)

r = 2.5 cm

Area = 3.14 × 2.5² = 19.63 cm²

10.)

d = 16 ft

Area = (3.14 × 16²) ÷ 4 = 200. 96ft²

11.)

d = 40 m

Area = (3.14 × 40²) ÷ 4 = 1256 m²

12.)

d = 10 cm

Area = (3.14 × 10²) ÷ 4 = 78.5 cm²

13.)

d = 3 m

Area = (3.14 × 3²) ÷ 4 = 7.07 m²

14.)

d = 12 in

Area = (3.14 × 12²) ÷ 4 = 113.04 in²

15.)

d = 16 ft

Area = (3.14 × 16²) ÷ 4 = 200. 96ft²

16.)

d = 7cm

Area = (3.14 × 0.6²) ÷ 4 = 0.28 km²

18.)

d = 2 cm

Area = (3.14 × 2²) ÷ 4 = 3.14 cm²

Answer:

La elevación de la carretera es de aproximadamente 0.999 metros.

Step-by-step explanation:

Cuando se dice que la pendiente es de 5 %, se quiere decir que la tangente del ángulo de elevación de la carretera es de 0.05. Trigonométricamente hablando, podemos calcular el ángulo de la pendiente como sigue:

[tex]\theta = \tan^{-1} 0.05[/tex]

[tex]\theta \approx 2.862^{\circ}[/tex]

La elevación de la carretera se determina mediante la función seno:

[tex]\sin \theta = \frac{h}{l}[/tex] (1)

Donde:

[tex]h[/tex] - Elevación de la carretera, medida en metros.

[tex]l[/tex] - Longitud de la carretera, medida en metros.

Si sabemos que [tex]l = 20\,m[/tex] y [tex]\theta \approx 2.862^{\circ}[/tex], entonces la elevación de la carretera es:

[tex]h = l\cdot \sin \theta[/tex]

[tex]h \approx 0.999\,m[/tex]

La elevación de la carretera es de aproximadamente 0.999 metros.

Considerando la regla de tres, la elevación de la carretera es de 1 metro.

La regla de tres es una forma de resolver problemas de proporcionalidad entre tres valores conocidos y un valor desconocido, estableciendo una relación de proporcionalidad entre todos ellos.

Es decir, lo que se pretende con ella es encontrar el cuarto término de una proporción conociendo los otros tres.

Si la relación entre las magnitudes es directa, es decir, cuando una magnitud aumenta, la otra también (o cuando una magnitud disminuye, la otra también), se debe aplicar la regla de tres directa.

Para resolver una regla de tres directa se debe seguir la siguiente fórmula, siendo a, b y c datos conocidos yx la variable a calcular:

a ⇒ b

c ⇒ x

Por lo tanto: [tex]x=\frac{cxb}{a}[/tex]

Una pendiente de 5% indica que por cada 100 m de longitud hay 5 m de pendiente.

Entonces podes aplicar la siguiente regla de tres: si por cada 100 m de longitud hay 5 m de pendiente o elevación, por 20 metros de longitud ¿cuál será la pendiente?

[tex]elevacion=\frac{20 metrosx5 metros}{100 metros}[/tex]

elevación= 1 metro

La elevación de la carretera es de 1 metro.

Answer:

28 cents roughly

Step-by-step explanation:

Given:

The expression is:

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\_\_\_+\dfrac{1}{19}n\right)+\left(-8+\_\_\_\right)[/tex]

                                          [tex]=\_\_\_n+\_\_\_[/tex]

To find:

The missing values.

Solution:

We have,

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)[/tex]

It can be written as

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\dfrac{11}{19}n+\dfrac{1}{19}n\right)+\left(-8+10\right)[/tex]

So, the values for the first two boxes are [tex]\dfrac{11}{19}n[/tex] and 10 respectively.

On simplification, we get

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\left(\dfrac{11+1}{19}n\right)+\left(2\right)[/tex]

[tex]\left(\dfrac{11}{19}n-8\right)+\left(\dfrac{1}{19}n+10\right)=\dfrac{12}{19}n+2[/tex]

So, the values for third and fourth boxes are [tex]\dfrac{12}{19}[/tex] and 2 respectively.

Answer:

rotations, translations, and reflections will not have an effect on a triangles size or shape. They just move it, rotate it, or mirror it.

Only a dilation will change a triangles size. Dilations scale a triangle up or down which change the triangles segment lengths but does not change it's angle sizes.

Answer:

Step-by-step explanation:

The perimeter of a rectangle with a length of 9x - 4 and a width of (5x + 2) will be 18x - 4.

Let W be the rectangle's width and L its length. The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be given as,

Perimeter of the rectangle = 2(L + W) units

The dimension of the rectangle is given as,

L = 9x - 4
W = 5x + 2

Then the perimeter of the rectangle is given as,

P = 2(L + W)

P = 2(9x - 4 + 5x + 2)

P = 2(14x - 2)

P = 18x - 4

The perimeter of a rectangle with a length of 9x - 4 and a width of (5x + 2) will be 18x - 4.

Step-by-step explanation: for infinitely many solutions the two lines must lie directly on top of one another- so same slope and same y-intercept

The lines in the graph of a system of equations that has infinitely many solutions will have The lines will have the same slope and the same y-intercepts.

A slope is a ratio that describes the steepness and the direction of a line.

The y-intercept is the point at which a line touches the y-axis. This means that x=0.

Thus we can say that the lines in the graph of a system of equations that has infinitely many solutions will have the same slope and the same y-intercepts. The correct answer is option B.

Answer:

First box: F (because we don't know the degrees Fahrenheit yet.

Second box: -62.1 (the degrees Celsius it tells us to find the equivalent of

Step-by-step explanation:

Solving the equation will go like this:

5/9(F - 32) = -62.1

multiply both sides by 9 to get rid of the fraction

5 (F - 32) = -558.9

divide both sides by 5

F - 32 = -111.78

add 32 to both sides

F = -79.78
