What is the height of the cone below?<br> - 3<br> - 9<br> - 27<br> - 75

Rasek [7]

$\bf \textit{volume of a cone}\\\\ V=\cfrac{\pi r^2 h}{3}~~ \begin{cases} r=radius\\ h=height\\ \end{cases}\implies V=\pi r^2\cdot \cfrac{h}{3}~~ \begin{cases} \pi r^2=&area~of\\ &circular\\ &base\\ \cline{1-2} \stackrel{B}{\pi r^2}=&5\\ V=&45 \end{cases} \\\\\\ 45=5\cdot \cfrac{h}{3}\implies 135=5h\implies \cfrac{135}{5}=h\implies 27=h$

The two rectangular prisms are similar.

Sophie [7]

Answer:

The volume of the larger rectangular prism is $648\ cm^{3}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its volumes is equal to the scale factor elevated to the cube

Let

z-----> the scale factor

x-----> the volume of the larger rectangular prism

y-----> the volume of the smaller rectangular prism

$z^{3}=\frac{x}{y}$

In this problem we have

$z=\frac{12}{4}=3$ ---> the scale factor is equal to the ratio of its corresponding sides

$y=24\ cm^{3}$

substitute and solve for x

$3^{3}=\frac{x}{24}$

$x=27*24=648\ cm^{3}$

A number x divided by -1 is at least -4

Vinil7 [7]

A number x divided by -1 is at least -4.

x / -1 ≥ -4

Multiply both sides by -1.

x ≤ 4

Remember, when multiplying or dividing by a negative, you must change the sign's direction.

What is the measure of FSM

disa [49]

Answer:

Whatever FSM is equal or congruent to.

Step-by-step explanation:

Since you didn't provide a picture or anything, I'll happily give you an example!

Example: FSM = ORH

This applies all the time.

F = O, S= R, M=H

If the measure of ORH is 19, then the measure of FSM will also be 19.

If the measure of FS is 14, for example, then OR will also be 14.

I hope this helps!!
