alex needs to buy compressed air to fill 5 empty cylindrical tanks for his store. each tank is 12 feet deep and has a radius of

Yanka [14]

Volume of a cylinder = the area of the base x height of the cylinder
Area of base = $\pi$ r^2
A = 6^2( $\pi$ )
A = 36 $\pi$
V = 36 $\pi$ x 12
V = 432 $\pi$

5 cylinders = 5V

5V = 5 x (432 $\pi$ )
5V = 2160 $\pi$

Final answer: Alex needs to buy 2160 $\pi$ or 6785.84 cubic feet worth of compressed air to fill all of the cylindrical tanks.

Using the following picture which side is the hypotenuse?

mylen [45]

Hi!

A <u>hypotenuse</u> is the longest leg in a right triangle.

A <u>right triangle</u> is a triangle that has one 90 degree angle.

The hypotenuse is always directly across from the right angle.

In pictures, right angles are represented by a square.

<u><em>Therefore, the side with the hypotenuse is side 3</em></u>, because we can see that the angle between side 1 and side 2 is the right angle, and the hypotenuse would be directly across.

A stick 43 inches long is broken into two pieces, so that one piece is twice as long as the other. How long are the two pieces?

allsm [11]

Answer:

One piece is $\frac{43}{3}$ inches and another piece is $\frac{86}{3}$ inches

Step-by-step explanation:

Let smaller piece length be $s$

Let larger piece length be $l$

Since total of two pieces is 43, we can write:

$s+l=43$

Also, one piece is twice as long as the other (so longer piece is definitely twice as the short piece), we can write:

$l=2s$

<em>Substituting equation 2 into equation one, we can solve for s:</em>

$s+l=43\\s+(2s)=43\\3s=43\\s=\frac{43}{3}$

<em>Thus longer piece is:</em>

$l=2s=2(\frac{43}{3})=\frac{86}{3}$
