The height of a cylinder is 8 centimeters. The circumference of the base of the cylinder is 20π centimeters. Which measurement is closest to the volume of the cylinder in cubic centimeters?

Answers

Answer: [tex]2514.28\ cm^3[/tex]

Step-by-step explanation:

Given

The height of the cylinder is [tex]h=8\ cm[/tex]

Circumference of the base is [tex]20\pi \ cm[/tex]

suppose 'r' is the radius of the cylinder

[tex]\Rightarrow 2\pi r=20\pi\\\Rightarrow r=10\ cm[/tex]

The volume of a cylinder is [tex]V=\pi r^2h[/tex]

[tex]\Rightarrow V=\pi \times 10^2\times 8=2514.28\ cm^3[/tex]

Calculating the Least Common Multiple :

Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 2

  Right_M = L.C.M / R_Deno = 1

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.

  L. Mult. • L. Num.      4 • 2

  ——————————————————  =   —————

        L.C.M              18  

  R. Mult. • R. Num.       x

  ——————————————————  =   ——

        L.C.M             18

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

4 • 2 - (x)     8 - x

———————————  =  —————

    18           18

When a fraction equals zero :

4.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 8-x

 ——— • 18 = 0 • 18

 18

Now, on the left hand side, the  18  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  8-x  = 0

Solving a Single Variable Equation:

4.2      Solve  :    -x+8 = 0

Subtract  8  from both sides of the equation :

                     -x = -8

Multiply both sides of the equation by (-1) :  x = 8

One solution was found :

x = 8

Jesse sent an email to 4 people for a school project. In her email, she requested
that each person copy and send the same email to 4 additional people.
If everyone continues to send the email as requested, which equation could be
used to determine the number of emails, y, that will be sent for a given round, x?
M. y = x^4
P.y = 4^x
R. y = 4x
a. y= 4/x

Answers

Answer:

P.y = [tex]4^{x}[/tex]

Step-by-step explanation:

From the given question, since Jesse sends the email to 4 people and the 4 people rebroadcast it to another 4 persons each. And this process continues for a required or given round x, then this is an example of an exponential function.

Thus, the number of emails sent for a given round can be expressed as;

                    y = [tex]4^{x}[/tex]

Therefore, the appropriate answer is y = [tex]4^{x}[/tex].

So that for four rounds (x = 4), the number of emails sent can be determined as;

y = [tex]4^{x}[/tex]

  = [tex]4^{4}[/tex]

y = 256

Answer: y=4^x
