What is the volume of the cylinder below? A. 72π units³

B. 36π units³

C. 45π units³

D. 90π units³

Answers

Answer:

Step-by-step explanation:

According to the diagram, the radius of this cyl. is 3 and the height is 4 (not 5). The formula for the volume of a cylinder is:

V = pi*r^2*h.

Here, that volume is V = pi*3^2*4, or 36 pi cubic units. That's Answer B.

The volume of the right cylinder is $\boxed{36\pi {\text{ unit}}{{\text{s}}^3}}.$

Further explanation:

The formula for the volume of the cylinder can be expressed as,

$\boxed{{\text{Volume}} = \pi {r^2}h}$

Here, ‘r” represents the radius of the cylinder and “h” represents the height of the cylinder.

Given:

The radius of the cylinder is ${\text{3 units}}$ and the height of the cylinder is ${\text{4 units}}$ and the slant height is $5{\text{ units}}$

The options of the volume are given as follows.

A. ${\text{72}}\pi {\text{uni}}{{\text{t}}^3}$

B. $36\pi {\text{uni}}{{\text{t}}^3}$

C. $45\pi {\text{uni}}{{\text{t}}^3}$

D. $90\pi {\text{uni}}{{\text{t}}^3}$

Explanation:

The volume of the right cylinder can be obtained as follows,

$\begin{aligned}{\text{Volume}} &= \pi {r^2}h\n&= \pi* {\left( 3 \right)^2} * 4\n&= \pi * 9 * 4\n&= 36\pi\n\end{aligned}$

The volume of the cylinder is $36\pi {\text{ unit}}{{\text{s}}^3}.$

Option A is not correct.

Option B is correct.

Option C is not correct.

Option D is not correct.

Hence, the volume of the right cylinder is $\boxed{36\pi {\text{ unit}}{{\text{s}}^3}}.$

What is an increasing or decreasing interval of a parabola? Is it like the vertex or turning point of the parabola? I don't remember. :(

Answers

Well first, an interval is a set of real numbers, usually x values. For example 0 ≤ x ≤ 1 is an interval. If the y values for the x values of the set increase as the x values increase, then the interval is increasing. If the y values for the x values of the set decrease as the x values increase, then the interval is decreasing. I hope that wasn't confusing, if you have questions, ask.

A coin is tossed 8 times. Which of the following represents the probability of the coin landing on heads all 8 times?

Answers

Answer:

$\large\boxed{\large\boxed{Probability=1/256\approx 0.0039}}$

Explanation:

Since, there are two possible outcomes for every toss (head or tail), the sample space for a coin tossed 8 times is 2×2×2×2×2×2×2×2 = 2⁸ = 256.

Landing on heads all 8 times is just one of the possible outcomes: HHHHHHHH ⇒ 1.

Hence, the probability is calculated from its own definition:

Probability = number of favorable outcomes / number of possible outcomes

$Probability=1/256\approx 0.0039\text{ }\leftarrow answer$

Answer:

1/256
