Find the volume formula is v=pi*r squared *h/3 <br> When r=6 and h=10

patriot [66]

377.14 units cubic.
Working;
v= $\frac{1}{3}$ *π* $r^{2}$ * $\frac{h}{3}$
v= $\frac{1}{3}$ * $\frac{22}{7}$ * $6^{2}$ * $\frac{h}{3}$
=377.14

The angle of depression of a point G on a horizontal ground from top T of an electrical pole is 25°. If the distance from G to t

Morgarella [4.7K]

Answer: 21 m

Step-by-step explanation:

Given

the angle of depression of point G is $25^{\circ}$

Distance from pole base to point G is 45 m

Suppose h is the height of the pole

From the figure, we can write

$\Rightarrow \tan 25^{\circ}=\dfrac{h}{45}\\\\\Rightarrow h=45\tan 25^{\circ}\\\Rightarrow h=20.98\approx 21\ m$

Where does y= 3X -2 and y=- X +2

Wittaler [7]

Answer:

When x = 1, these two equations are equal

Step-by-step explanation:

To do this, we need to set each equation equal to the other

The setup looks like

$3x-2=-x+2$

Now we can solve for x

$3x-2=-x+2\\\\3x=-x+4\\\\4x=4\\\\x=1$
