How to find the ratio of the volume of a cone to the volume to a cylinder

dangina [55]

The volume of a cone, V(cone), is given by the following formula:

V(cone) = (1/3)Bh, where B is the area of the circular base and h is the height of the cone. The area B of the base is given by the formula B = πr², where r is the radius of the circular base; Therefore, substituting for B, the volume of a cone becomes:

Find two numbers that have 2, 3, and 5 as factors. What other factors do those two numbers have in common?

Advocard [28]

To find the first number, just multiply the three numbers together.
$2*3*5 \\ 6*5 \\ 30$

To find the second number, multiply the three numbers together along with another number (this number can be anything).
$2*3*5*4 \\ 6*5*4 \\ 30*4 \\ 120$

<u>What They Have in Common:
</u><u />- All numbers will be even, since you are multiplying by 2.
- All numbers will end in a zero, since you are multiplying by 5 and also 2.

Simplify the expression. Write the answer with positive exponents only. Assume the variable represents a nonzero real number.

luda_lava [24]

Answer:

$\frac{1}{w^{29}}$

Step-by-step explanation:

The given expression is $\frac{w^{-7}(w^{-9})^2}{w^4}$ .

Since, $w^{-7}=\frac{1}{w^7}$

And $w^{9}=\frac{1}{w^9}$

Expression will become,

$\frac{w^{-7}(w^{-9})^2}{w^4}=\frac{\frac{1}{w^7}(\frac{1}{w^9})^2}{w^4}$

$=\frac{\frac{1}{w^7\times w^{18}}}{w^4}$

$=\frac{\frac{1}{w^{(7+18)}}}{w^4}$

$=\frac{1}{w^{25}}\times \frac{1}{w^4}$

$=\frac{1}{w^{25}\times w^4}$

$=\frac{1}{w^{29}}$

Therefore, Simplified form of the given expression will be $\frac{1}{w^{29}}$ .
