What is the volume of this cone?
Answer:
(1/3)πr2h.
Step-by-step explanation:
Volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
Base surface area of a cone (a circle):
B = πr2
Total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
The diameter of a circle is 0.82 inches. What is the approximate area of the circle?
Answer:
.53
Step-by-step explanation:
your diameter is .82,so divide it by two to get your radius
.82 / 2 = .41
A = [tex]\pi[/tex] r ^2
A = [tex]\pi[/tex] .41 ^2
A = .53
Answer:
0.53
Step-by-step explanation:

what is the value of x in simplest radical form?
Answer:
25
Step-by-step explanation:
For these types of problems you'll need the Pythagorean theorem (woohoo..). This amazing formula looks like: a^2 + b^2 = c^2. The a and b in this formula are the legs of the triangle, the straight non-diagonal lines. The c stands for the hypotenuse which is the diagonal line.
Since you have both of the legs we can go ahead and plug that into our equation: 15^2 + 20^2 = c^2.
NOTE: It doesn't matter which leg you plug into which variable! Just make sure it's not c!
With exponents, it just means to multiply the number by itself. 15^2 is the same as 15(15). So, simplifying the equation, we get: 225 + 400 = c^2.
This part is pretty straightforward. I mean, unless you don't remember addition... Adding it together, you will get 625 = c^2.
This part kinda requires a calculator if you don't know all of your square roots. Luckily, this is a perfect root and goes into 25.
And that, my friend, is your answer. Hope this helped :)

Helpppppp please asp
I believe the answer is D: 6×9÷3.
The question is a word problem, and they are asking you to put it into a numerical problem, meaning with numbers. 6 times 9 divided by 3 put into a numerical equation is 6×9÷3.
If this is incorrect, please, don't refrain to tell me. Thank you.
Is this right??? Please help!!

If two polygons are similar, they are congruent.
Always true sometimes true or never true?
Answer:
It is true.
Step-by-step explanation:
congruent polygons have the exact same size and are a perfect match because all corresponding parts are congruent (equal). ... This means that if two polygons are similar, then their corresponding angles are congruent

PLSSS HELP MEEE DUDE HELP MEEEEEE Marshall High School’s community service club will be selling baked goods as a fundraiser. The club members plan on making cupcakes and cookies. There will be 5 cookies made for every 2 cupcakes made. The club members plan on making 280 total baked goods.
Plot the point on the coordinate plane below that represents the total number of cupcakes and the total number of cookies that the community service club members plan on making for the fundraiser.
To plot the point, click the pencil tool and select the thickest brush size.
Answer:
See Explanation
Step-by-step explanation:
Let the number of cookies be x and the number of cupcakes be y.
If the total is 280, then
[tex]5x + 2y = 280[/tex]
Subtract 5x from both sides
[tex]5x - 5x + 2y = 280 - 5x[/tex]
[tex]2y = 280 - 5x[/tex]
Make y the subject
[tex]y = 140 - \frac{5}{2}x[/tex]
See attachment for graph
Any of the following equation can be plotted on the graph (they literally represent the same thing)
[tex]5x + 2y = 280[/tex]
[tex]2y = 280 - 5x[/tex]
[tex]y = 140 - \frac{5}{2}x[/tex]
Answer:
its 200 cookies and 80 cupcakes
Step-by-step explanation:
my explanation is the kid right next to me told me the answer and the teacher said his was right
HELPPPPPPPPMEEEEE with math please
Answer:
Step-by-step explanation:
The "key" to this is to recognize that the two lines have to be the same length, they put the drawing on it's side to make it harder to see that. :/ But another way to see this is that it's an isosceles triangle and you know the two legs that they are asking us about have to be the same length, knowing that.. we can set the two expression equal to each other
3x - 10 = 2x
now solve for x
3x - 10 -2x = 2x - 2x ( subtracting 2x from both sides )
3x - 2x - 10 = 0
x - 10 = 0
x - 10 + 10 = 0 + 10
x = 10 ( yay)

C(n) = -7 + 6(n - 1)c(n)=−7+6(n−1)c, left parenthesis, n, right parenthesis, equals, minus, 7, plus, 6, left parenthesis, n, minus, 1, right parenthesis Find the 4^\text{th}4 th 4, start superscript, start text, t, h, end text, end superscript term in the sequence.
Answer: The 4th term is 11.
Step-by-step explanation:
The given sequence: [tex]C(n) = -7 + 6(n - 1)[/tex] which represents the nth term.
To find 4th term.
Put n=4, we get
[tex]C(4) = -7 + 6(4 - 1)\\\\\Rightarrow\ C(4) = -7 + 6(3)\\\\\Rightarrow\ C(4) =-7+18\\\\\Rightarrow\ C(4) =11[/tex]
Hence, the 4th term is 11.
