Answer:

Step-by-step explanation:

Given,

Volume of cone ( v ) = 27 π

Radius ( r ) = 3 cm

Height of cone ( h ) = ?

Now, let's find the height of cone:

Volume of cone = $\frac{\pi {r}^{2}h }{3}$

plug the values

$27\pi = \frac{\pi \: {3}^{2} \: h \: }{3}$

Evaluate the power

$27\pi = \frac{\pi \times 9 \times h}{3}$

Divide 9 by 3

$27\pi = 3\pi \: h$

Divide both sides of the equation by 3π

$\frac{27\pi}{3\pi} = \frac{3\pi \: h}{3\pi}$

Calculate

$9 = h$

Swipe the sides of the equation

$h = 9$ cm

Hope this helps..

HELP PLZ! I do not understand this!!

PART 1
If I have graph f(x) then graph f(x + 1/3) would translate the graph 1/3 to the left.

For example, I have f(x) = x².Then
f(x + 1/3) = (x + 1/3)²

I draw the graph of f(x) = x² and the graph of f(x) = (x + 1/3)² on cartesian plane to know what's the difference between them.

PART 2
If I have graph f(x) then graph f(x) + 1/3 would translate the graph 1/3 upper.

For example, I have f(x) = x².Then
f(x) + 1/3 = x² + 1/3

I draw the graph of f(x) = x² and the graph of f(x) = x² + 1/3 on cartesian plane to know what's the difference between them.

SUMMARY
f(x+1/3) ⇒⇒ <span>f(x) is translated 1/3 units left.
f(x) + 1/3 </span>⇒⇒ <span>f(x) is translated 1/3 units up.</span>
