Answer:

-\frac{3}{4}  meters

Step-by-step explanation:

From the answer choices, we basically need to find which of them is between   -\frac{1}{2}  and  -1\frac{2}{3}

<em>Converting all of them to decimals would make it really easier:</em>

<em />

<em>So we need to find number between -0.5  and -1.67</em>

<em />

<em>Answer choice A is -2.33</em>

<em>Answer choice B is  -0.75</em>

<em>Answer choice C is  -0.25</em>

<em>Answer chioce D is  -1.83</em>

If the dimensions of the following cylinder are quadrupled, what will be the volume of the new similar cylinder?
Alik [6]

Answer:  First option is correct.

Explanation:

Since we have given that

Radius = 11 inches

Height = 14 inches

Now, according to question, we have mentioned that all the dimensions of the cylinder is to be quadrupled i.e. four times.

Then,

Radius is given by

4\times 11=44 inches

Height is given by

14\times 4=56\ inches

As we know the formula for " Volume of cylinder ":

V=\pi r^2h\\\\V=3.14\times 44\times 44\times 56=340426.24\ in^3

Hence, our volume of new similar cylinder is 340426.24 cubic in.

Therefore, First option is correct.
