What is the approximate volume of the cone?

Use 3.14 for π.

A 1206 cm³

B 2170 cm³

C 3260 cm³

C 6510 cm³

Answers

Answer:

A. 1206 cm³

Step-by-step explanation:

We have a cone and are asked to find the approximate volume of it.

Keep in mind we are using π for 3.14

The forumla of a cone is V = πr²[tex]\frac{h}{3}[/tex]

We know the radius = 12

and the height = 8

Substitute :

V = π12²[tex]\frac{8}{3}[/tex]

Since these are multiplied with each other, we can first start off with multiplying the fraction, including with factoring 12²:

V = [tex]\frac{2^4*3^2*8\pi }{3}[/tex]

Cancel the common factor - 3 :

V = [tex]2^4 * 8 * 3\pi[/tex]

Multiply 8 and 3π :

V = [tex]2^4 * 24\pi[/tex]

Solve the exponent :

V = [tex]16 * 24\pi[/tex]

Multiply :

V = [tex]384\pi[/tex]

Multiply for the final answer :

1205.76 cm³

which can be rounded up to

A. 1206 cm³

Ms. Charles asked her students how many minutes they spent studying for a test the night before the test was given. She found that the time students spent studying and their test scores had a positive correlation. Which scatterplot below shows this relationship?

Answers

It’s the first graph, the top one. It shows that the more minutes and studying the higher the test grade is.

Answer:

Option A

Step-by-step explanation:

C and D are scattered showing no pattern, Therefore, it is either A or B. I say it's not B due the the fact more studying minutes made even less test grades. So A is the only option left.

Answers

Answer:

A.) 127.16π

Step-by-step explanation:

Volume of a cylinder = πr²h

Radius, r = 3.4m

Height, h = 11m

Pi = π

Find the volume in terms of pi

Volume of a cylinder = πr²h

= π * (3.4)² * 11

= π * 11.56 * 11

= 127.16π³

The correct answer is

A.) 127.16π

Answers

Answer:

I hope this helps you

Step-by-step explanation:

To define the time of flight equation, we should split the formulas into two cases:

Launching projectile from the ground (initial height = 0)

t = 2 * V₀ * sin(α) / g.

Launching projectile from some height (so initial height > 0)

t = [V₀ * sin(α) + √((V₀ * sin(α))² + 2 * g * h)] / g.

In ABC m /_A = 65° and m/_B= 80°
Select the triangle that is similar to ABC

Answers

Answer:

C is the correct answer.

Step-by-step explanation:

All of the angles in a triangle add up to 180 degrees. 65+80=145 and when you do 180-145, you get 35 degrees. You can check to see if it's correct by adding 35, 65, and 80 together.

[tex]65+80=145[/tex]

[tex]180-145=35[/tex]

[tex]35+65+80=180[/tex]

The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC. Option C is correct.

What exactly is a triangle?

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

ΔDEF

∠F=80°

∠F=35°

The sum of the angle of the triangle DEF is;

∠D+∠E+∠F=180°

∠D=180°-115°

∠D=65°

In ABC

/_A = 65°

/_B= 80°

∠A+∠B+∠C=180°

∠D=180°-145

∠D=35°

The opposite angle of the triangle is similar.ΔDEF is similar to ΔABC.

Hence,option C is correct.

2/x =3/4 what is x? im doing a math test help

Answers

X=8/3 or 2.666 is the answer

Answer:

[tex]x=\frac{3}{4}[/tex]

Step-by-step explanation:

First, we know we want to get x all by itself. So, let's multiply it by 2.

[tex]\frac{2}{x}(2) = \frac{3}{4}(2)\\[/tex]

Then we have:

[tex]x=\frac{3}{4}(2)[/tex]

Now, we have to simplify the right side of the equation, so, let's rewrite it.

[tex]x=\frac{3*2}{4*2}[/tex]

All we have to do now is simplify.

[tex]x=\frac{6}{8}[/tex]

Luckily (and ironically) both the numerator and denominator are divisible by 2, so...

[tex]x=\frac{3}{4}[/tex]
