Answer: 67.94 cm^2

Step-by-step explanation:

The volume of a cylinder equals the base area multiplied by the height.

Therefore, the volume would be equal to 21.23cm*3.2cm = 67.936 cm^2

Rounded to the nearest hunderedth, the volume would be 67.94 cm^2

$\bf \sqrt{20k^3}\qquad 
\begin{cases}
20=2\cdot 2\cdot 5\\
\qquad 2^2\cdot 5\\
k^3=k^{2+1}\\
\qquad k^2\cdot k^1
\end{cases}\implies \sqrt{2^2\cdot 5\cdot k^2\cdot k}\implies 2k\sqrt{5k}$

Domain and range of the inequality y<√x+3 +1

Margaret [11]

The domain of the given inequality is y>1.

<h3>What is Inequality?</h3>

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions.

Here, given inequality:

y < $\sqrt{x+3}+1$

Related equation:

y = $\sqrt{x+3}+1$

The equation defined as,

x+3 > 0

x > -3

In the given inequality, the sign of inequality is <, it means the points on the boundary line are not included in the solution set. Thus, -3 is not included in the domain.

So, the domain of the given inequality is x>-3.

We know that,

$\sqrt{x+3} \geq 0$
