Answer:
The correct answer for me was true
Step-by-step explanation:
Si el ancho de 100 cm de la hoja se convierte en la altura del cilindro, la longitud de 42 cm debe ser su circunferencia.[matemáticas]\ C = 2 \pi r \implica r = \frac{C}{2 \pi} \approx \boxed{6.68 \ \mathrm{cm}}.[/matemáticas]
[matemáticas]V = \pi r^2h = \dfrac{C^2 \cdot h}{4 \pi} = \dfrac{\left(42 \ \mathrm{cm}\right)^2 \cdot 100 \ \ mathrm{cm}}{4 \pi} \approx \boxed{14\,037.5 \ \mathrm{cm^3}}.[/math]

Answer:
The evaluated answer to this equation is 19.
Step-by-step explanation:
<em>2r² + 3s³ - r² + 4t² - r²</em>
In the problem, we are given values for the variables in the equation.
<em>r = -2</em>
<em>s = -3</em>
<em>t = 5</em>
Let's plug these numbers into the equation.
<em>2(-2)² + 3(-3)³ - (-2)² + 4(5)² - (-2)²</em>
First, simplify the exponents.
<em>2(4) + 3(-27) - (4) + 4(25) - (4)</em>
Next, multiply the numbers starting from left to right.
<em>8 + (-81) - 4 + 100 - 4</em>
Add 8 and -81 together.
<em>-73 - 4 + 100 - 4</em>
Subtract 4 from -73.
<em>-77 + 100 - 4</em>
Add -77 to 100.
<em>23 - 4</em>
Subtract 4 from 23.
<em>19 </em>
<u>So, your final simplified answer to this equation is 19.</u>
Answer:
y = 9 + 4x/3
x = -27/4 + 3y/4
*everything that looks like x/y is a fraction, -27/4 is entirely negative
