Answer:

V = 54π or V = 169.56 units³

Step-by-step explanation:

The volume of a cylinder is given by the formula:

V = πr²h

If we use 3.14 as pi we get this:

V = (3.14)×(3)²×(6)

V = 3.14×9×6

V = 3.14×54

V = 169.56

Since it is volume the units will be units³

So our final answer is 169.56 units³

If you wanted an exact in pi form you would do the same steps but not simplify pi:

V = πr²h

V = π×(3)²×6

V = π×9×6

V = 54π

Answer:

-1        <---------- slope

Step-by-step explanation:

Since the formula is y2-y1=x2-x1

since the points are (-2,6) and (0,4)

Enter the points in

4-6/0-(-2)   ----> (2 negatives is a +)

-2/2= -1

The slope is -1

If the slope is -1, the equation will be y=-x+b

then, enter one of the given points, (-2,6)

6=2+b

b=4

So the slope int form is y=-x+b

to find the point slope form,

y-y1=m(x1-x) <--- formula

So,

take 1 point (-2,6) and enter it in

y-6=-1(x+2)   <--- point slope form

to graph y=-3x+2

make x=0 and enter into the equation

y=0+2

y=2

so if x=0, y=2 so thats one point (0,2)

and lets say if x=-6 (enter into equation)

y=-3(-6)+2

y=18+2

y=20

so if x=-6, y=20 (another point) (-6,20)

you only need 2 points to graph a line

so enter (0,2) and (-6,20) and draw a line

In a survey, one out of five people named blue as their favorite color. Three out of ten named red. If 1,100 people were include
bagirrra123 [75]
1/5 = x/1100                                                    

5x = 1100
x = 1100 ÷ 5
x = 220

So 220 people named blue as fav.

3/10 = x/1100

3x = 1100
x = 1100 ÷ 3
x = 366.6666.... = 367

So 367 people chose red

The lengths of the two diagonals of a rhombus are 6 cm and 8 cm. Find the length of its perimeter (in
adelina 88 [10]

Answer:

<em>The perimeter of the rhombus is 20 cm</em>

Step-by-step explanation:

<u>Perimeter of a Rhombus</u>

Given the lengths of the two diagonals of a rhombus, let's call them a and b,  the perimeter of the rhombus is given by:

P=2\sqrt{a^2+b^2}

The values of the diagonals provided by the question are a=6 cm, b=8 cm, thus the perimeter is:

P=2\sqrt{6^2+8^2}

P=2\sqrt{36+64}

P=2\sqrt{100}=2*10

P=20\ cm

The perimeter of the rhombus is 20 cm
