A line segment has two endpoints unlike a line where a line is infinite with no end! :) Think of a line segment essentially just being two points on a line. :)

Find the volume of this cylinder. Please help

algol13

Answer:

$\boxed {\boxed {\sf 384 \ ft^3}}$

Step-by-step explanation:

The volume is the space an object occupies. The volume formula for a cylinder is provided and it is:

$V= \pi r^2 h$

Where:

r= radius
h= height

The radius is the distance from the center of the circle to the edge, and it is 4 feet. The height is 8 feet. We are told to use 3 for pi.

r= 4 ft
h= 8 ft
π= 3

Substitute the values into the formula.

$V= (3)(4 \ ft)^2 (8 \ ft)$

Solve the exponent.

(4 ft)²= 4 ft * 4 ft = 16 ft²

$V= (3)(16 \ ft^2)(8 \ ft)$

Multiply the three numbers together.

$V= 48 \ ft^2 (8 \ ft)$

$V= 384 \ ft^3$

The volume of the cylinder is approximately <u>384 cubic feet.</u>

What is the distance between (-2 1/2, -3) and (1, -3)

Igoryamba

Answer:

Step-by-step explanation:

(-2 1/2, -3) = (-5/2 , -3) & (1, -3)

$Distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(1-[\frac{-5}{2}])^{2}+(-3-[-3])^{2}}\\\\ =\sqrt{(1+\frac{5}{2})^{2}+(-3+3)^{2}}\\\\ =\sqrt{(\frac{7}{2})^{2}} \\\\=\frac{7}{2}\\\\=3\frac{1}{2}$

Two families are shopping for a camping trip. The first family buys 3 flashlights and 4 sleeping bags at a cost of $118. The sec

Sliva [168]

Answer:

3x +4y = 118

5x+6y =180

y= $25

Step-by-step explanation:

Let x = the cost of a flashlight

Let y = the cost of a sleeping bag

3x +4y = 118

5x+6y =180

Multiply the first equation by -5

-5(3x +4y) = -5*118

-15x -20y = -590

Multiply the second equation by 3

3(5x+6y) =3*180

15x + 18y = 540

Add the modified equations together.

We are using elimination to eliminate the variable x

-15x -20y = -590

15x + 18y = 540

----------------------------

-2y = -50

Divide by -2

-2y/-2 = -50/-2

y =25

Each sleeping bag costs $25
