Explain what the diameter of a circle is. If you had the diameter of a circle, how could you solve for the circumference?
The diameter can be thought of as the width of the circle, more or less. More accurately, it's the distance from one point on a circle, through the center, to a point on the opposite side.
If we had a circle at point A, and some point on the edge of the circle point B, then line AB will form a third point C. Point C is on line AB and on the circle. Segment BC is a diameter.
We can measure the diameter with a straight line ruler, but we cannot do the same with the perimeter of the circle. The circumference is just a fancy name for "perimeter". Specifically, it only applies to circles. The way I remember it is that "circle" has "circ" in it, and so does "circumference". Furthermore, we can erase some letters of "circumference" to end up with "fence", which would go along an outer perimeter in a lot of cases. Overall, "circumference" makes me think of "circle fence".
How can we find the perimeter of a circle? Well we could use a cloth ruler to wrap around the edge of the circle. We'd have to make sure that none of the bendable ruler is out of place. So things could get tricky.
To find the circumference with a formula, we'll use this one here
C = pi*d
where pi = 3.14 approximately and d is the diameter
----------------------
For example, let's say the diameter is d = 10 feet. That would lead to a circle perimeter of....
C = pi*d
C = 3.14*10
C = 31.4
The circumference is approximate because pi = 3.14 is approximate. The units for the circumference in this case are in feet, so the distance around this particular circle is about 31.4 feet.

4.4s + 6.2 = 8.8s - 1.8
please help
Answer:
s = 1.81
Step-by-step explanation:
4.4(1.81)+6.2=8.8(1.81)-1.8
plug in and multiply if you'd like to clarify :)
Answer:
=Steps
4.4s+6.2=8.8s−1.8
Multiply both sides by 10
4.4s· 10+6.2· 10=8.8s· 10−1.8· 10
Refine
44s+62=88s−18
Subtract 62 from both sides
44s+62−62=88s−18−62
Simplify
44s=88s−80
Subtract 88s from both sides
44s−88s=88s−80−88s
Simplify
−44s=−80
Divide both sides by −44

A stadium has 8,436 seats that are divided into 12 different sections. Each section has the same number of seats.
How many seats are in each of the 12 sections? please show the work
Answer:
703
Step-by-step explanation:
You divide the 8436 by 12.
1. You can't divide the 8 by 12 so skip that
2. You can divide 84 by 12 so you get 7
3. Bring down the 3 (you have 0 as a remainder). You can't divide that so put a 0
4. Bring down the 6 and divide that (36) and you get 3
5. Your final answer would be 703.

10. If ABCD is a kite, DB=48 in. and CE=7 in. find DC. *
49 in.
23 in.
25 in.
47 in.
Answer:
25 in.
Step-by-step explanation:
DEC is a right triangle. <DEC is a right angle.
(DE)² + (EC)² = (DC)²
DE = ½DB = ½(48 in.) = 24 in.
(24 in.)² + (7 in.)² = (DC)²
576 in.² + 49 in.² = (DC)²
(DC)² = 625 in.²
DC = 25 in.

Answer:
5. 4186.67 in³
6. 1436.03 ft³
7. 3052.08 cm³
Step-by-step explanation:
5. Determination of the volume of the sphere.
Radius (r) = 10 in
Pi (π) = 3.14
Volume (V) =?
V = 4/3πr³
V = 4/3 × 3.14 × 10³
V = 4/3 × 3.14 × 1000
V = 4186.67 in³
6. Determination of the volume of the sphere.
Radius (r) = 7 ft
Pi (π) = 3.14
Volume (V) =?
V = 4/3πr³
V = 4/3 × 3.14 × 7³
V = 4/3 × 3.14 × 343
V = 1436.03 ft³
7. Determination of the volume of the sphere.
We'll begin by calculating the radius. This can be obtained as follow:
Diameter (d) = 18 cm
Radius (r) =?
r = d/2
r = 18/2
r = 9 cm
Finally, we shall determine the volume of the sphere. This can be obtained as follow:
Radius (r) = 9 cm
Pi (π) = 3.14
Volume (V) =?
V = 4/3πr³
V = 4/3 × 3.14 × 9³
V = 4/3 × 3.14 × 729
V = 3052.08 cm³

What is the relationship between how Jews were portrayed to the public and their persecution during the holocaust?
Hint: Find how they were portrayed to the public by Hitler and then follow that up with How were they persecuted during the Holocaust?
Answer:
Step-by-step explanation:
This is actually in the wrong place. It should probably be in English or History, but I'll answer it anyway.
You need to start by seeing the way they were portrayed in cartoons, in writing (mainly newspapers), on the radio, in speeches and on the streets. Start with the Bible. The Old Testament was about the law mostly and behavior as much as anything. The people who lived and were governed by the OT generally were very pious unless they were rebellious sinners.
The New Testament is a slightly different matter. In most of Europe the peasantry thought the Jews were Christ Killers. That thought was dominent throughout the Middle Ages. It isn't true. Jesus was a Jew, so were the disciples, so were the huge crowds that followed Him to at least hear what he had to say.
It was only the ruling classes (The Pharisees, the Sadducees, and the scribes and teachers), that were not fond of Jesus. But that fact was not emphasized. Out of that picture and the displacement of the Jews after the Temple was destroyed, grew the caricatures of what the Jews were.
Anti Semitism was quite common in Europe. Most people fell for the propaganda that said the Jews were the spawn of the Devil. It became easy to kill those that were felt to be evil.

Consider the following vectors: y = (2,4), v = (-1, -1), and w = (7.-2).
What is the vector for 3u + v- 2w in component form?
(20,15)
(10,7)
(-6,1)
(-9.15)
Answer:
(-9.15)
Step-by-step explanation:
We are given these following vectors:
u = (2,4), v = (-1,-1), w = (7,-2)
What is the vector for 3u + v- 2w in component form?
3u + v - 2w = 3(2,4) + (-1,-1) - 2(7,-2) = (6,12) + (-1,-1) + (-14,4) = (6 - 1 - 14, 12 - 1 + 4) = (-9, 15)
The answer is (-9,15).

At which root does the graph of f(x) = (x + 4)(x + 735 cross the x-axis?
9514 1404 393
Answer:
both of them: x = -4, x = -735
Step-by-step explanation:
The meaning of "real root" is that the graph intersects the x-axis at that value of x. If the degree of the root is odd, the graph crosses there. (If the degree of the root is even, the graph only touches the x-axis.)
f(x) = (x +4)(x +735)
has real roots at x = -4 and x = -735, so crosses the x-axis in those places.
