What is the volume of the cylinder below radius 8 height 3 in pi units Answer choices: A)96pi unit^3 B)192pi unit^3 C)225pi unit

WARRIOR [948]

Hey!

The formula for finding volume of a cylinder is: π · r² · h

$r = 8 \\ r^{2} = 8 \times 8 = 64$

$h = 3$

Now multiply

$\pi \times 64 \times 3 = 192\pi$

<em>Your answer is B)192π units³</em>

Good luck and hope this helps! :)

Find x so that (x,-14) is a solution to 2x+3y=12

Monica [59]

Answer:

Question:

Find $x$ so that $(x,-14)$ is a solution to $2x+3y=12$ .

Step-by-step explanation:

So we are asked to replace $y$ with -14 and solve for $x$ in the equation:

$2x+3y=12$ .

$2x+3y=12$ with $y=-14$ :

$2x+3(-14)=12$

$2x-42=12$

Add 42 on both sides:

$2x=54$

Divide both sides by 2:

$x=27$ .

So the $x$ -coordinate that corresponding to $y=-14$ is $27$ .

Verify that:

$(27,-14)$ is a point satisfying $2x+3y=12$ .

Replace $x$ with 27 and $y$ with -14:

$2(27)+3(-14)=12$

$54+-42=12$

$12=12$ is true so our work must be right.
