What is the volume of the following cylinder?

tigry1 [53]

If the diameter is 12, then its radius is half that, or 6.

$\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=6\\
h=15
\end{cases}\implies V=\pi (6)^2(15)\implies V=540\pi$

Each year three space shuttles are launched, two in June and one in October. If each shuttle is known to occur without a delay i

Veronika [31]

Answer:

0.271 or 27.10%

Step-by-step explanation:

If the present month is January, in 16 months there will be three space shuttles launched (two in June and one in October).

The probability that at least one launch will be delayed is 100% minus the probability that no launch will be delayed:

$P(delay>0) = 1 - P(delay=0)\\P(delay>0) = 1 -0.90^3\\P(delay>0) = 0.271$

The probability that at least one of the launches in the next 16 months will be delayed is 0.271 or 27.10%.

Can. Y’all help with this

solmaris [256]

Answer:

Your Answer Would be the 3rd Option.

Step-by-step explanation:

The Initial Value is : 4. All you have to do is look for when the x = 0

ROC: 1/2. Minutes =x, Inches= Y. To find ROC, take

Y2 - Y1

----------

X2 - Y1

Replacing those with numbers:

5 - 4

-------

2 - 0

Your ROC is 1/2 .

Equation:

y= 1/2x + 4

Know that The 4 is the initial value, so it's always in that spot. Your ROC is always Next to the x, which also means it's the slope.
