What is the volume of a cylinder?The volume of a cylinder is the capacity of the cylinder, which determines how much material it can hold. In geometry, a specific volume of a cylinder formula is used to calculate how much of any quantity, liquid or solid, can be immersed in it uniformly. A cylinder is a three-dimensional shape with two identical congruent and parallel bases.
The given equation gives us the formula to calculate the volume (V) of the any given cylinder with the help of it's height(h) and base radius (r).
Given, [tex]$\quad V=\pi r^2 h$[/tex]
Divide both sides by h.
[tex]\frac{V}{h}[/tex] = [tex]\frac{\pi r^2 h}{h}[/tex]
V/h = π/[tex]$r^2$[/tex]
Divide both sides by [tex]$r^2$[/tex].
[tex]\frac{V}{r^2 h}[/tex] = [tex]\frac{\pi r^2}{r^2}[/tex]
π = [tex]\frac{V}{r^2 h}[/tex]

A coin is filmed using stop-motion animation so that it appears to move.
b. Describe the translation from A to C using a translation vector.
The translation of a coin from A to C using a translation vector is ;
Vector AC = (7, 3).
What is termed as translation?A translation in arithmetic a structure left or right and/or up or down. The translated shapes appear to be of the same size as the initial structure, indicating that the shapes are congruent.
Whenever the shape is moved to the left by k units, replace x with x - k.Whenever the shape is moved to the right by k units, replace x with x + k.Whenever the shape is moved by k units, replace y with y + k.Whenever the shape is moved by k units, replace y with y - k.Now, as per the given question.
See the given figure.
The coordinates if the points A and C are.
A = (-3, -1) and C = (4, 2)
The translation from A to C is estimated as;
AC = (4 + 3) ,(2 + 1)
Translation AC = (7, 3)
Thus, the given point A shifts 7 units to its right and then 3 units up to the point C.

The beta club is selling gift baskets to raise funds. Each basket sells for $13 and costs $6.50 to make. Write and expression to model a profit the beta club earns for each basket b sold.
The expression that models a profit P the beta club earns for each basket b sold is:
P = 6.50b
or
P = 13b - 6.50b
Given,
The beta club is selling gift baskets to raise funds.
Each basket sells for $13 and costs $6.50 to make.
We need to write an expression to model a profit the beta club earns for each basket b sold.
How do find profit?The profit is given by:
Profit = Selling price - cost price.
We have,
Selling price = $13
Cost price = $6.50
Find the expression for the profit.
The expression can be written as:
P = b ( 13 - 6.50 )
= 6.50b
or
P = 13b - 6.50b
Where b = number of baskets.
Thus the expression that models a profit P the beta club earns for each basket b sold is:
P = 6.50b

Probability:
Probability defines the possibility of the event.
And it can be calculated as,
Probability = favorable event / total event
Given,
Point A is chosen at random on [tex]\bar{BE}[/tex].
Here we need to find the the probability of the following event.
P(A is on [tex]\bar{DE}[/tex]).
Let us consider the following image, in order to solve this.
Based on the image we have identified that the probability of the event P(A is on [tex]\bar{DE}[/tex]) is calculated by dividing the length of DE by the length of BE.
So, the probability of the event P(A is on [tex]\bar{DE}[/tex]) is,
P(A is on [tex]\bar{DE}[/tex]) = (length of DE) / (length of BE)
Apply the values then we get,
P(A is on [tex]\bar{DE}[/tex]) = 9 / ( 5 + 12 + 9)
P(A is on [tex]\bar{CD}[/tex]) = 9 / 26

Solve each system by elimination.
2a + 3b = 12 , 5a - b = 13
By elimination, the solution of the system of equations, 2a + 3b = 12 and 5a - b = 13, is (a , b) = (3 , 2).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in a and b, a variable should be eliminated by adding/subtracting the two equations.
Multiply first equation 2 by 3.
5a - b = 13 (equation 2)
15a - 3b = 39
Adding the two equations will eliminate the variable b.
2a + 3b = 12 (equation 1)
15a - 3b = 39 (equation 2)
17a = 51
a = 3
Substitute the value of a to any of the two equations and solve for b.
2a + 3b = 12 (equation 1)
2(3) + 3b = 12
3b = 12 - 6
3b = 6
b = 2
Hence, the solution of the system of equations is (a , b) = (3 , 2).

A company sells two different sizes of exercise balls. The ratio of the diameters is 15: 11 . If the diameter of the smaller ball is 55 centimeters, what is the volume of the larger ball? Round to the nearest tenth.
The volume of the larger ball the company sells is 220,893.2 cubic centimeters.
If the diameter of the smaller ball is 55 centimeters, and the ratio of the diameters of two different sizes of exercise balls is 15 : 11, then
diameter of larger ball / diameter of smaller ball = 15 : 11
diameter of larger ball = 15 (55 cm) / 11
diameter of larger ball = 75 cm
If the diameter of the larger ball is 75cm, and half of the diameter is the radius, then:
r = D/2
r = 75cm/2
r = 37.5 cm
Solving for the volume of the larger exercise ball using the formula for the volume of the sphere given by:
V = 4/3πr^3
V = 4/3π(37.5 cm)^3

What are the center and radius of the circle with the given equation?
b. x²+y²-6 x+14 y=8
The equation of the circle x^2 + y^2 - 6x + 14y = 8 has a radius of √66 and a center located at (3 , -7).
The standard form of the equation of circle is given by
(x - h)^2 + (y - k)^2 = r^2
where (h , k) is the location of the center and r is the radius of the circle.
On the other hand, the general form of the equation of circle is given by
x^2 + y^2 + Dx + Ey + F = 0
where D = -2h, E = -2k, and F = h^2 + k^2 -r^2.
If the equation of the circle in general form is x^2 + y^2 - 6x + 14y = 8, then the coefficients are:
D = -6
E = 14
F = -8
If D = -2h and D = -6, then

Solve the following:

Answer:
no solution
Step-by-step explanation:
- (6x + 6) + 2 = - 6x - 3 ← distribute parenthesis on left side and simplify
- 6x - 6 + 2 = - 6x - 3
- 6x - 4 = - 6x - 3 ( add 4 to both sides )
- 6x = - 6x + 1 ( add 6x to both sides )
0 = 1 ← not possible
this indicates the equation has no solution
Answer:
No Solution, 0 = 1
Step-by-step explanation:
a) Simplify both sides of the equation.
−(6x + 6) + 2 = −6x − 3
−6x+ −6 + 2 = −6x + −3
(−6x) + (−6 + 2) = −6x − 3
−6x + −4 = −6x − 3
−6x − 4 = −6x − 3
b) Add 6x to both sides.
−6x − 4 + 6x = −6x − 3 + 6x
−4 = −3
c) Add 4 to both sides.
−4 + 4 = −3 + 4

Describe the similarities and differences between a common difference and a common ratio.
The similarity between common difference and common ratio is that both are used to find the next term, but common difference is added while common ratio is multiplied.
Common difference (d) is defined as the difference between consecutive terms in an arithmetic sequence. It is determined by subtracting the term from the preceding term. For example, in an arithmetic sequence 2, 5, 8, 11,…, the common difference is 5-2=3 or 8-5=3.
The sequence will be: a, a+d, a+2d, a+3d,… a+nd.
In the general form:
d=an -an-1, where an is the nth term and an-1 is the preceding term.
Common ratio (r) is defined as the quotient between consecutive terms in a geometric sequence. It is determined by dividing the term by the preceding term. For example, in an geometric sequence 2, 4, 8, 16,…, the common ratio is 4/2=2 or 8/4=2.
The sequence will be: a, ar, ar^2, ar^3,…ar^n.
In the general form:
r=an/an-1, where an is the nth term and an-1 is the preceding term.

The given polynomial, 6•x² + 12•x + 6, can be factored by rearranging and looking for the common factors to give;
6•x² + 12•x + 6 = 6•(x + 1)²
How can the given polynomial be factored?The given polynomial is presented as follows;
6•x² + 12•x + 6
The coefficients in the terms and the constant have a common factor of 6, which gives;
6•x² + 12•x + 6 = 6•(x² + 2•x + 1)
x² + 2•x + 1 = x² + x + x + 1
x² + x + x + 1 = x•(x + 1) + 1•(x + 1)
x•(x + 1) + 1•(x + 1) = (x + 1)•(x + 1) = (x + 1)²
Therefore;
x² + 2•x + 1 = (x + 1)²
6•(x² + 2•x + 1) = 6•(x + 1)²
