please help me iv been having trouble with this problem

Answer:

25.12

Step-by-step explanation:

the formula of a cone is pi r^2 * h/3

r = radius and h = height

the radius is 2 and the height is 3

and the question says use 3.14 instead of pi so

we have

3.14 * 2^2 * 6/3

2*2 or 2^2 = 4

3.14 * 4 * 6/3

6/3 = 2

3.14 * 4 * 2

4*2 = 8

and 8 * 3.14 is 25.12

Answer:

A

Step-by-step explanation:

Answer:

Positive

Step-by-step explanation:

Since x > 0 =  x is positive

Since y < 0 = y is negative

Product of positive and negative number is negative.

Therefore,

       xy = - xy

    - (xy) = -( -xy)

    - (xy) = xy              [since product of negative and negative is positive]  

Answer:

x-1

Step-by-step explanation:

Area= x^2+4x-5

Width= x+5

Area= Length*breadth

x^2+4x-5=length*x+5

Length=x^2+4x-5/x+5

Therefore, length= x-1

Answer:

x-1

Answer:

So lets convert the fractions to improper:

3/2 and 9/4

And for it to be easier to plot, make them decimals (divide):

1.5 and 2.25

The step here is 0.125 (1/8 (the amount of lines between a number))

Plot:

1.5, is 1 1/2 and 2.25 is 2 1/4 on the number line..

Lets convert the fractions to improper:

1 1/2 = 3/2 = 1.5.

2 1/4 = 9/4 = 2.25.

3/2 and 9/4

And for it to be easier to plot, make them decimals (divide):

1.5 and 2.25

Therefore, 1.5, is 1 1/2 and 2.25 is 2 1/4 on the number line.

The triangle below has a perimeter of 27\text{ cm}27 cm27, start text, space, c, m, end text.

What is the length of one side of the triangle?

All 333 sides are the same length.

Answer:

-1<-0.25

With -1>0.25 you have a negative(-1) and a positive(0.25) the negative will always be less than the positive proving the equation wrong

Moving onto -1<-0.25 this one is a little trickier because they both have a negative so this is where you look at the number line and see which number is closer to 0 and whichever number is is greater meaning this is the correct answer.

Answer:

Answer: D

Step-by-step explanation:

Let's just go through it.

No parallel sides A B C (if you believe the diagram) D F

Not regular (and no parallel sides) (if you believe the diagram) B C D F

No Lines of symmetry (that means that if you put a mirror on a line of symmetry) what you see as an image will be the same as what there is in front  of the mirror. C D F

Has a reflex angle. (Just to remind you, it is an angle greater that 180 but less than 360

That lets out everybody but D.

Answer: D

Step-by-step explanation:

1. C and G have one set of parallel sides, and E, H, and I have two sets of parallel sides so they can be ruled out.

2. Regular shapes have sides that are all the same length and angles that all measure the same. A can be ruled out in addition to I which was already ruled out.

3. B can be ruled out now.

4. The only one with a reflex angle (greater than 180 degrees) is D.

15 hundreds = star

Step-by-step explanation:

Move 1 thousand into hundreds place with the 5 hundreds that were already there. 5 plus 10 =15. We just don't usually think of it like that because of place value.

Answer:

I guess the answer is or the ★=2

Step-by-step explanation:

because if u add like now add 2+5=7,which is 7 tens in both side or 3 the one of thousand like 3+2 u get 5 the one of hundreds so that is how i get 2
