please help me thank you sooooo much ( also if you take my points
I'm reporting you)

The answer is C.

Here is the formula for volume of cone:

[tex]\frac{1}{3} \pi r^{2} h[/tex]

where r is the radius and h is the height.

[tex]\pi r^{2}[/tex] is the area of the "base" or the fomula for calculating the area of a circle.

In your question, the height is given, but you don't know the radius. However, it could be found using the circumference of 8.4pi cm.

The formula for the relationship between circumference, diameter, and the constant pi:

[tex]C =\pi d[/tex]

where C is the circumference and d is the diameter of the circle.

Substitute the numbers in:

[tex]8.4 \pi = \pi d[/tex]

Remove [tex]\pi[/tex] from both sides of the equation:

[tex]d=8.4[/tex]

Diameter is the length across the circle, while radius is half of diameter.

Hence, [tex]r =4.2[/tex]

Now that you have all the "information" you need to calculate the cone's volume, substitute the numbers into the formula:

[tex]\frac{1}{3} \pi * 4.2^{2}* 14[/tex]

You should get  [tex]82.32\pi cm^{2}[/tex]  as your answer. The [tex]\pi[/tex] is left alone because the question stated "in terms of pi", but if that weren't stated pi should be replaced with 22/7 or 3.14 depending on the question.

I hope this clears up any confusion you might have! If not, feel free to leave a comment with your question.

Answer:

t+25=45

Answer to the equation: 20

Step-by-step explanation:

The answer to the equation is to because you would subtract 45 by 25 and get the answer witch is 20. Hope this helps! :)

Answer:

I would have to say J.

Step-by-step explanation: Now a square has 4 sides, all equal as well. (I am on PC so I cant do the little 2 on J.) so 2 times little 2 is 4, because with these for example, 2 times little 3 would be 2 times 2 times 2. So 2 times little2 -9 is the most reasonable answer!

Answer:

B.

Step-by-step explanation:

Both equations use x squared

Answer:

The common facor is x-3.

Step-by-step explanation:

The first expression can be factored with a difference of squares, x+3 and x-3. You can check that by multiplying them together to get x²-9. Knowing that you need a common factor, one that works for both expressions, you can immediately eliminate A and B. The second expression, x²-5x+6, has to share one of these two factors. To factor this, you find the numbers that multiply to the c term and add to the b term. (Ax²+bx+c) so b is -5 and c is 6. All you have to do is find out which two numbers add to -5 and multiply to 6. You start with factors of 6, which are +-6 and +-1, and +-3 and +-2. Say you try 6 and 1 first. The b term is negative, so these two added have to add to a negative number, which means positive 6 and positive 1 won´t work. The only way to add to -5 is to add 1 to -6 or -6 to 1, but multiplying those together gives you -6, and you need positive 6 in the c term. That leaves you with -2 and -3. they add to -5, and multiply to -6, which means that your common term is x-3. Test this by expanding your result, (x-2)(x-3), if you get the original expression theyre both factors.

Answer:

I)3   II)4x

Step-by-step explanation:

for the infinite number of solutions you need to make both equations on both sides equal

but in the one for no solution you need to make one number is equal to another number, which is wrong in Math, that's why there's no solution in it

Answer:

It should be, You can make 6 packages

Step-by-step explanation:

There's a lot to type but I swear I did work lol, lmk if it's right

last  bubble one i guess ok

The answer is a and b.

Here's the way to check:

Since all the numbers follow a constant sequence, it is possible to use division. Minus the first term, then divide it by the pattern of the sequence.

For a, 512 - 8 = 504

The pattern from a is each number is increased by 7. So,

504 ÷ 7 = 72

The number itself you count is not important. The point is that the number could be divided fully without remainder. This means 512 will appear in the sequence.

Repeat the above steps for b and c:

512 - 23 = 489

489 ÷ 3 = 163

It can be divided without remainder, 512 appears in this sequence.

512 - 12 = 500

500 ÷ 12 = 41.66666

Since C is a decimal ( there is remainder ), the number 512 does NOT appear in the sequence.

However, if you want to know the logic of WHY this works, I won't be able to give you a satisfying answer. Hope this helps you.
