A = πr² = π(d/2)² = 3.14(3/2)² = 7.065 m²The area of a square with a side length of 3 meters:
A = a² = 3² = 9 m²The difference:
9 - 7.065 = 1.935 m²The square has greater area by 1.935 m²

3a+4(5a - 4)=
5b -2(5a -b) + 10a
Answers
Answer:
17a - 16
7b
Step-by-step explanation:
Given the following expressions
3a+4(5a - 4)=
Expand
3a + 4(5a)- 4(4)
= 3a + 20a - 16
= 17a - 16
For the expression
5b -2(5a -b) + 10a
Expand
5b - 2(5a)-2(-b) + 10a
5b - 10a + 2b + 10a
= 5b + 2b -10a + 10a
= 7b + 0
= 7b

<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

Ayuda es un examen determinado raíz cuadrada entera de cada número y el residuo en cada caso º60 º86 º96 Raíz:_residuo:_ raíz:__residuo__ raíz__residuo
Answers
Answer:
Los pasos para calcular la raíz cuadrada entera y su residuo o resta se dará en la explicación;
Step-by-step explanation:
-60: Para saber exactamente cuál es su raíz cuadrada entera debemos buscar entre que cuadrados perfectos se encuentra comprendida este valor;
Tenemos que 7x7=49 y 8x8 = 64 (60 está comprendido entre 7 y 8) ,pero como la raíz de 49 se aproxima más a 60 entonces la raíz de 60 es 7 y su residuo o resta será el valor que falta para llegar a 60; así que tenemos:
[tex]\sqrt{60}[/tex]=7 ; residuo: 60-49 =11
-86: 9x9 =81 ;81 se aproxima más a 86 ,entonces la raíz cuadrada entera de 86 es 9 y su residuo es 5:
[tex]\sqrt{86}[/tex]=9; residuo : 86-81= 5
-96: 9x9=81 ; 81 por tanteo se aproxima más a 91,entonces la raíz cuadrada entera de 96 es 9 y su residuo es 15.
[tex]\sqrt{96[/tex]= 9x9 =81 ; residuo : 96-81= 15.

A man 6 feet tall casts a shadow that is 11 feet long. A building casts a shadow of 139 feet long. The building is tall. Round your answer to the nearest 10th
Answers
Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.
[tex]\dfrac{\text{Height of man}}{\text{Height of man's shadow}}=\dfrac{\text{Height of the building}}{\text{Height of building's shadow}}[/tex]
Let x be the height of the building.
[tex]\dfrac{6}{11}=\dfrac{x}{139}[/tex]
Multiply both sides by 139.
[tex]\dfrac{6}{11}\times 139=x[/tex]
[tex]\dfrac{834}{11}=x[/tex]
[tex]75.8181...=x[/tex]
[tex]x\approx 75.8[/tex]
Therefore, the building is 75.8 feet long.

Answer:
x = 13, angle = 37
Step-by-step explanation:
The full angle will be a right angle, so 90 degrees.
You are given 53, on one side, so you just need to find the other bit.
Here, you can do 90 - 53 and get 37, which has to be equal to your unknown angle.
2x + 11 = 37
2x = 26
x = 13
Answer:
x=13
Step-by-step explanation:
we know that the 2 angles add up to a 90° right angle
53+ (2x+11) = 90
solving that, we're left with 2x= 26
26÷ 2= 13=x
