eldted. Go to volume of a cylinder C and volume of a cone e, and complete each step below.Question 1Drag the orange points on th

e cylinder and the cone to change their radii and heights. (Make sure the Freeze height checkboxes are not checked.)Set equal radii and heights for the cylinder and the cone, and note their respective volumes. Record the volumes for a few sets of heights andradii, and calculate the ratio of the volumes in each case. Remember, make sure the height and radius of the cone and the cylinder are the samein each pair. (You might see some discrepancies in the tool due to rounding of decimals.) Round your calculations for ratio to the hundredthsplace.

The volume of a cone is computed as follows:

V\text{ of cone}=\pi r^2\frac{h}{3}

where r is the radius and h is the height of the cone.

The volume of a cylinder is computed as follows:

V\text{ of cylinder=}\pi r^2h

where r is the radius and h is the height of the cylinder.

Substituting with r = 1 and h = 1, the volumes are:

\begin{gathered} V\text{ of cone}=\pi\cdot1^2\cdot\frac{1}{3}=\pi\cdot1\cdot\frac{1}{3}\approx1.05 \\ V\text{ of cylinder=}\pi\cdot1^2\cdot1=\pi\approx3.14 \end{gathered}

And the ratio of volumes is:

\frac{V\text{ of  cone}}{V\text{ of cylinder }}=\frac{1.05}{3.14}\approx0.33

Substituting with r = 2 and h = 4, the volumes are:

\begin{gathered} V\text{ of cone}=\pi\cdot2^2\cdot\frac{4}{3}=\pi\cdot4\cdot\frac{4}{3}\approx16.76 \\ V\text{ of cylinder=}\pi\cdot2^2\cdot4=\pi\cdot4\cdot4\approx50.26 \end{gathered}

And the ratio of volumes is:

\frac{V\text{ of cone}}{V\text{ of cylinder }}=\frac{16.76}{50.26}\approx0.33

Can someone please help with the last problem
Brut [27]

Answer:

  18x +9h

Step-by-step explanation:

Such problems are tedious, but not difficult. The trick is to avoid making mistakes in the algebra.

  \dfrac{f(x+h)-f(x)}{h}=\dfrac{(9(x+h)^2)-(9x^2)}{h}\\\\=\dfrac{9(x^2+2xh+h^2)-9x^2}{h}=\dfrac{18xh+9h^2}{h}=\boxed{18x+9h}

Write an expression for the calculation the difference of the products of 5 and 2 and 5 and 1
oee [108]
Let's review the terminology.  A product is what you get when you multiply two numbers.  So, the product of 5 and 2 is basically "5*2," and the product of 5 and 1 is "5*1."

The difference means when you subtract one from the other.  So, the difference of 5*2 and 5*1 means "(5*2)-(5*1)".  (Note: I put in parentheses to make sure the reader understands that 5*2 is separate from 5*1.  5*2-5*1 is confusing: you might not know what to do first!)

So, "(5*2)-(5*1)" can be your answer, OR you can simplify it further by actually doing the multiplication: "10-5".  If you want the answer, just subtract--the expression is equal to 5.

Answer: "<span>(5*2)-(5*1)" OR "10-5" OR "5"</span>
