La finca de federico tiene un area de 576 m2 , en ella ha sembrado naranja y cafe, 3/8 de la finca estan sembrados de naranjas y el resto de cafe, ¿ cual es el area de la finca que estan sembrada por cafe?

Answers

Responder:

360 m²

Explicación paso a paso:

Área de la finca = 576 m²

Porción de café =

Ración de naranja = 3/8

Español

Área de la granja de naranjos:

3/8 * área de la finca

3/8 * 576m²

= 216 m²

Dado que el resto se utiliza para el café;

Área utilizada para café;

Área total: área utilizada para naranja

576m² - 216m²

= 360 m²

This composite figure is created by placing a sector of a circle on a rectangle. What is the area of this
composite figure? Use 3.14 for it. Show all calculations that lead to the answer and include units. Please provide steps to prove your answer.

Answers

Answer:

148.12m²

Step-by-step explanation:

At first, lets find the area of rectangle.

length = 14m

breadth = 6m

Area of rectangle = length x breadth

= 14 x 6

= 84m²

Now, For the area of sector of the circle,

Given angle (a) = 34

radius = 14m

Area of the sector = a / 360 x pi x r²

= 34/360 x 3.14 x 14²

= 34 / 360 x 3.14 x 196

= 58.12m²

Now adding both areas,

84 + 58.12 = 142.12m²

Segment of a circle is the part of the circle. The total area of the composite figure is 142.1544 m².

What is the area of the segment of a circle?

The area of the segment of the circle is given by the formula,

[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]

As it is given that the composite figure is made up of a circular segment and a rectangle, therefore, we will find the area of the rectangle and the area of the circular segment individually.

Area of the rectangle

The area of the rectangle is the product of its length and breadth, therefore, the area is,

[tex]\rm \text{Area of the rectangle} = Length \times breadth[/tex]

                                [tex]= 14 \times 6\\\\=84\rm\ m^2[/tex]                

Area of the sector of the circle

[tex]\rm \text{Area of the rectangle} = \pi r^2 \times \dfrac{\theta}{360}[/tex]

                                   [tex]= \pi \times 14^2 \times \dfrac{34}{360}\\\\=58.1544\rm\ m^2[/tex]

The total area of the composite figure

The total area of the composite figure

= Area of rectangle + Area of the segment of the circle

= 84 + 58.1544 m²

= 142.1544 m²

Hence, the total area of the composite figure is 142.1544 m².

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

Let's solve your equation step-by-step.

11x − 2x + 15 = 8 + 7 + 9x

Step 1:

Simplify both sides of the equation.

11x − 2x + 15 = 8 + 7 + 9x

11x + −2x + 15 = 8 + 7 + 9x

( 11x + −2x ) + ( 15 ) = ( 9x ) + ( 8 + 7 )

( Combine Like Terms )

9x + 15 = 9x + 15

9x + 15 = 9x + 15

Step 2:

Subtract 9x from both sides.

9x + 15 − 9x = 9x + 15 − 9x

15 = 15

Step 3:

Subtract 15 from both sides.

15 − 15 = 15 − 15

0 = 0
