+23PTS! PDF Volume question -_- find diameter from the cylinder. I got 9 answer is 6 how???

Serga [27]

Answer: See below

Explanation:

For this question, we are given the volume, and we want to find the diameter. We have to work backwards to get our radius, then to find the diameter.

$V=\pi r^2h$ (Volume of cylinder)

$72\pi =\pi r^2h$ (The π cancel out)

$72 =r^2(8)$ (Plug in h=8)

$9=r^2$ (Divide 8)

$r=3$ (Square root of 9 is 3)

Now that we have our radius, we can find our diameter.

$d=2r$ (Equation for diameter)

$d=2(3)\\$ (Plug in r=3)

$d=6yards$ (Multiply)

Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's asserti

nadya68 [22]

No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect

<h3>Perpendicular lines</h3>

In order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:

For the slope of lm:

$m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1$

For the slope of ln:

$m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\$

For the slope of mn:

$m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\$

If any of the two lines is perpendicular, hence the triangle lmn is right-angled.

To check, we will take the product of the slopes and see if it is equivalent to -1.

Product of slope lm and ln

$m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2$

Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect
