quedan con una altura de 6 cm?
Se debe remover aproximadamente 140.848 centímetros cúbicos de madera para reducir las esferas a anillos con altura de 6 centímetros.
En esta cuestión se precisa calcular el volumen de la esfera y sustraer los volúmenes de dos casquetes esféricos de igual cantidad [1] y un cilindro recto respectivo a la operación de taladrado. [2] La cantidad de madera a remover queda definida por la siguiente expresión:
[tex]V = \frac{2\pi}{3}\cdot h^{2}\cdot (3\cdot R - h) + \pi\cdot r^{2}\cdot (2\cdot R-2\cdot h)[/tex] (1)
Donde:
[tex]V[/tex] - Volumen removido de madera, en centímetros cúbicos.[tex]h[/tex] - Altura del casquete esférico, en centímetros.[tex]R[/tex] - Radio de la esfera, en centímetros. [tex]r[/tex] - Radio del agujero, en centímetros.Si sabemos que [tex]h = 1\,cm[/tex], [tex]R = 4\,cm[/tex] y [tex]r = 2.5\,cm[/tex], entonces la cantidad de madera a remover es:
[tex]V = \frac{2\pi}{3}\cdot (1\,cm)^{2}\cdot [3\cdot (4 \,cm) - 1\,cm] +\pi\cdot (2.5\,cm)^{2}\cdot [2\cdot (4\,cm)-2\cdot (1\,cm)][/tex]
[tex]V \approx 140.848\,cm^{3}[/tex]

The expression two pi parentheses RH plus R to the power of two parentheses represents the total surface area of a cylinder with height H in radius R what is the surface area of the cylinder with a height of 6 cm and a radius 2 cm
Answer:
100.6cm2
Step-by-step explanation:
The mathematical expression wil become
[tex]2\pi(rh + {r}^{2} )[/tex]
The TSA of a cylinder is
[tex]2\pi \: rh + \pi {r}^{2} + \pi {r}^{2} [/tex]
When simplified, we have
[tex]2\pi \: rh + 2\pi {r}^{2} = 2\pi(rh + {r}^{2} )[/tex]
So indirectly, the expression is the same as total surface area of a cylinder.
So all you have to do is substitute the height and radius into any of the formulas .
[tex]2 \times \frac{22}{7} ( (2 \times 6) + {2}^{2} )[/tex]
[tex]2 \times \frac{22}{7} (12 + 4) \\ 2 \times \frac{22}{7} \times 16 \\ \frac{22 \times 2 \times 16}{7} \\ \frac{22 \times 32}{7} \\ \frac{704}{7} = 100.57 {cm}^{2} \\ = 100.6 {cm}^{2} [/tex]

If 4/5 of the population of a certain town is
considered to be middle class and the population
of the town is 2,000, how many people are
considered middle class?
Hi! I'm happy to help!
Our town is composed of 2,000 people. Of those 2,000 people, 4/5 of them are middle class. The word 'of' usually means multiplication when it is in a word problem. So, we will multiply 2,000 by 4/5. When multiplying a whole number, we just multiply it by the numerator (top) and leave the denominator. (bottom)
2,000×4
8,000
8,000/5
Fractions are just a different way of putting division, so we can change this to a division problem:
8,000÷5=
1,600
1,600 of the people are middle class.
I hope this was helpful, keep learning! :D

jim invested his savings in two investment funds. the amount he invested in fund A was $3000 less than the amount he invested in fund B. Fund A returned a 8% profit and Fund B returned a 7% profit. How much did he invest in Fund B, if the total profit from the two funds together was $960?
Answer:
$8000
Step-by-step explanation:
Let it be that investment in A is x dollars, then Jim invested in B x+3000.
x/100*8=0.08x- the profit from A, (x+3000)/100*7= 0.07x+210
0.08x+0.07x+210=960
0.15x=750
x=750/0.15= 5000
5000+3000=8000dollars- investment in B
The required amount invested in Fund A is $5000, and in Fund B is $8000.
What are simultaneous linear equations?Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.
Here,
Let the amount invested in fund A be x, and the amount invested in fund b be y.
x = y - 3000 - - - - - - - - - - -(1)
0.08x + 0.07y = 960 - - - - - - - - (2)
From the equation, 1
[y - 3000]0.08 + 0.07y = 960
y = $8000
Now,
x = 8000 - 3000
x = 5000
Thus, the required amount invested in Fund A is $5000, and in Fund B is $8000.

The price to mail a letter at the post office is $.49 for the first ounce and $0.21 for each additional ounce. Ann paid $1.96 to mail his letter. How much did the letter weigh?
Answer:
the answer is 8 oz
Step-by-step explanation:
well it says for the first ounce is $0.49 so $0.49 is your first number, then you're trying to figure out how many $.21
2.then to make this easier you subtract $0.49 from $1.96 and that's is $1.47
3.then all you need to do is divide $1.47 By .21 cents anand you should get 7.
4.but don't forget the $0.49 for the first ounce, then 1 ounce add it to the 7 and It will equal 8 oz in total

The length of a rectangle is twice its width.
If the perimeter of the rectangle is 54 yd, find its length and width.
Answer:
Length 18 yds, Width 9 yds
Step-by-step explanation:
2x + 2x + x + x = 54
Combine like terms
6x = 54
Divide both sides by 6
x = 9
Plug 9 into equation above
2(9) + 2(9) + 9 + 9 =
18 + 18 + 18 = 54
