Okay so I have multiple questions that I need help with so I will put them below and you will get more points! Once you know the answer put in the comments Answer one is so I no what it is answer two is etc.Question number one:
Find the volume of a cylinder with a diameter of 8 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank)
Question 2:
Given a soda can with a volume of 21 and a diameter of 6, what is the volume of a cone that fits perfectly inside the soda can? (Hint: only enter numerals in the answer blank)
Question 3:
Given a cube with a volume of 27 cm3, what is the volume of a square pyramid that can fit perfectly inside the cube?
A)3cm3
B)6cm3
C)9cm3
D)12cm3
If you can answer all of these you will be getting 20 points only one of these you get 5 and only two of these 15 points so answer all three to get more points.

Vcone=(1/3)hpir^2
d/2=r
so
1.
d=8
r=8/2=4
h=3r
h=3(4)
h=12
V=12*3.14*4^2
V=602.88 in^2
2. cone that fits has same base area and therefor same radius
d=6
r=6/2=3
rcone=3
find height of can
V=hpir^2
21=h*3.14*3^2
21=h*3.14*9
0.7431=h
so
cone height=0.7431
radius=3
V=(1/3)(0.7431)(3.14)(3^2)
V=7 cubic units
3.
same base
find dimentions
s=s=s
V=s^3

The system of equations has no solution.
What is equation?
An equation is arrangement of variables and coefficient which provides to understand given statement in form of numbers .That means a mathematical statement consisting of an equal symbol between two algebraic expressions that have the same value.
How to solve?
Given equation y=5x+10 and other equation y=5x+2
to check if two have any solution possible we will substitute value and check if RHS=LHS or not
∴y=5x+10=5x+2
=5x+10=5x+2
⇒0= -8
hence RHS≠ LHS hence no solution is possible

you can easily see that they are contrary to the equation . We not solve them . However prove it.
by substitution .
We substitute the value of y from the first equation to the second equation
y = 5x + 10
y = 5x + 2
y = 5x + 10
5x + 10 = 5x + 2
y = 5x + 10
5x - 5x = 2 - 10
y = 5x + 10
0 ≠ -8
or by opposing coefficients
y = 5x + 10 [* (-1)
y = 5x + 2
-y = -5x - 10
y = 5x + 2
----------------- sum
0 ≠ -8

The 10 times greater is the value of 3 in 300 than the value of 3 in 30 after using the concept of fraction.
What is a fraction?
Fraction number consists of two parts, one is the top of the fractionnumber which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
How many times greater is the value of 3 in 300 than the value of the 3 in 30
Let x be the number of times the value of 3 in 300.
The equation can be framed:
3x = 300
x = 300/3
x = 100
Let y be the number of times the value of the 3 in 30:
The equation can be framed:
3y = 30
y = 30/3
y = 10
Take the fraction:
x/y = 100/10
x/y = 10
x = 10y
Thus, the 10 times greater is the value of 3 in 300 than the value of 3 in 30 after using the concept of fraction.

The first thing you need to do is understand what you're looking for ...
what a 'solution' means, what it looks like, and how you even know
when you have it. I'm not sure you're there yet.
The 'answer' or the 'solution' to the problem is a number. It's the number
that 'x' must be in order for that line at the top to be a true statement. There's
only one possibility.
To find it, you can do anything you want to either side of the problem, as long as
you do exactly the same thing to the other side too. With that ability, here's how
to 'figure out the problem', and find the answer:
The original problem: 3x + 8 = 26 + x
Subtract 8 from each side:
3x = 18 + x
Subtract 'x' from each side:
2x = 18
Divide each side by 2 :
x = 9 .
That's what the answer looks like, and that's what the answer is.
' 9 ' is the ONLY number you can write in place of 'x' in the problem,
and have the problem read true.
I'll show you what I mean. Let's take the original problem
3x + 8 = 26 + x
and let's write ' 2 ' wherever we see 'x' :
3 (2) + 8 = 26 + 2
3 (2) means 3 times 2, and that's 6 .
So now we have
6 + 8 = 26 + 2
Do the addition on each side, and we have
14 = 28 .
That's nonsense. 14 is not equal to 28 . The reason that happened
is because we put the wrong number in place of 'x' . When we put the
correct number in place of 'x', the left side will be equal to the right side.
To 'figure out the problem' means to find out what that number must be.
For this particular problem, it's 9 .
Most important rule in algebra, do what you did on one side to the other when simplifying equations
So using this rule ∧ just do exactly what is says. First subtract 8 from the side with the 3x and then subtract onto the 26. Now you have 3x =18 + x. Now just subtract x from the side with the 18 and then subtract it to the side with the 3x, getting 2x = 18, now just divide by 2 on both and get x = 9. That's your answer

The area of the given Circle C is; 324π
What is the area of the circle?
From the attached diagram, we see that;
WX is the radius of circle X and is equal to 8 units
Similarly, ZY is radius of circle Y and is equal to 10 units.
Thus, diameter of circle X = 8 * 2 = 16 units
Diameter of circle Y = 10 * 2 = 20 units
Thus;
Diameter of circle C = 20 + 16 = 36 units
Area of Circle C = π * 36²/4
Area of Circle C = 324π
