Answer:

  • A) The radius is 4 m

Step-by-step explanation:

Volume of cylinder formula:

  • V = πr²h

<h3>Given</h3>

  • V = 64π,
  • h = 4 m

Find r by substituting given values:

  • 64π = πr²*4
  • 64π = 4r²π
  • 16 = r²
  • r = √16
  • r = 4 m

Correct choice is A.

Answer:

radius, r = 4 meters

Volume of cylinder:

  • \sf V = \pi (radius)^2 (height)

Here provided with:

  • radius = ?
  • height = 4 m
  • volume = 64π

Substituting these values in the formula:

\sf  \rightarrow \pi (r)^2 (4) = 64\pi

\sf  \rightarrow 4\pi (r)^2 = 64\pi

\sf  \rightarrow  r^2 = 64\pi /4\pi

\sf  \rightarrow  r^2 =16

\sf  \rightarrow  r=\sqrt{16}  = 4

What is the correct description for the graph of the inequality, y &lt; 42 – 3?
Varvara68 [4.7K]
Answer: The graph is a solid line. The test point (0,0) does not satisfy the inequality.


Explanation:
The line is solid because it is less than or EQUAL TO. The test point does not satisfy because if you replace y and x with 0, it will not be true. 0 is not less than or equal to -3, therefore (0,0) does not satisfy the inequality.

How do we solve this?<br> (No need to find x)
Genrish500 [490]

Answer:

Hi,

Step-by-step explanation:

We can't solve that but reduce it to the same denominator.

\dfrac{x+5}{x}+\dfrac{x+8}{x-1}\\\\=\dfrac{(x+5)(x-1)+x(x+8)}{x(x-1)}\\\\=\dfrac{x^2+5x-x-5+x^2+8x}{x(x-1)}\\\\=\dfrac{2x^2+12x-5}{x(x-1)}\\

Find a linear equation with two variables that, together with the
Mila [183]

Answer:

10x+5y=2

Step-by-step explanation: You have the equation 10x+5y=1 and from the problem, we are trying to find an equation that does not produce a solution with 10x+5y=1. To do this know 1 is your y-intercept and if you put 10x+5y=1 into slope-intercept form you'll get y=-2x+1/5. Solve the problem know that you can use any number besides 1 on the right side and have the same slope to fit the question. What I mean is that let's say I have 10x+5y=2, I put it into a slope-intercept form I'll have y=-2x+2/5. The two equations y=-2x+1/5 and y=-2+2/5 will not meet because their slopes are PARALLEL. So in short have a different y-intercept but the same slope to not get a solution. Additional note you could have other y-intercepts such as 3,4,5,6,7,8, or 9 in your standard form equation 10x+5y= to get a equation that does not make a solution with 10x+5y=1.
