↪Hola user_____________

⭐Here is Your Answer...!!!

____________________

↪SURFACE AREAS AND VOLUMES

↪The VOLUME of any object is nothing but the the capacity to hold the amount of substance inside it . It defines the Amount of substance that can occupied bythe object inside it ..

↪Volume = Base Area × Height

↪thus for the Cylinder ; Volume of cylinder = Pi(R^2) × H

↪thus volume = 3.14 × R^2 × H

↪thus here given as R = 4 cm and H = 12cm

↪Volume = 3.14 × 16 × 12= 602.88 cm^3

thus

↪the Volume of the Cylinder = 602.88 cm^3

Answer:

=192 pi  cm^3

  602.88 cm^3

Step-by-step explanation:

We know the radius of a cylinder is 4 and the height is 12

We need to find the volume.

The volume is how much material can be put into the space.

Think of filling a can with water.  How much water can we put in the can?

That will be the volume.

V cyclinder = pi * r^2 h,  which is the area of the base  times the height

                   = pi * 4^2 *12

                   = pi * 16*12

                     =192 pi  cm^3

When we approximate pi as 3.14

                     = 3.14 (192)

                    602.88 cm^3

Answer:

Given f(x) and g(x), please find (fog)(X) and (gof)(x) f(x) = 2x   g(x) = x+3    

Given f(x) and g(x), please find (fog)(X) and (gof)(x)

Quick Answer

(fog)(x) = 2x + 6

(gof)(x) = 2x + 3

Expert Answers

HALA718 eNotes educator| CERTIFIED EDUCATOR

f(x) = 2x

g(x) = x + 3

First let us find (fog)(x)

(fog)(x) = f(g(x)

            = f(x+3)

              = 2(x+3)

              = 2x + 6

==> (fog)(x) = 2x + 6

Now let us find (gof)(x):

(gof)(x) = g(f(x)

           = g(2x)

          = 2x + 3

==> (gof)(x) = 2x + 3

Help pleaseeeeeeeeeeeeee!!!!!!!!!!!!!!!! T^T

1 + (-5/8) = 3/8

Explanation: If the coffee wasn’t drank it would’ve been at fraction 1 (or 100%)

Since he drank 5/8 of it. The coffee left is now 1-(5/8)

But since the question has asked to give the equation in addition format. Put a plus sign in between the two.

Therefore,
1 + (-5/8)

Solve it,
= 1-(5/8)
= (8-5)/8
= 3/8

Hence the equation is:

1 + (-5/8) = 3/8.

The complete question is
Susan and Steven are cousins. The sum of their ages is 33. The difference between three times Steven's age and half of Susan's age is 36. Find <span>the age of Susan and Steven

let
x-----> </span>Susan's age
y---->  Steven's age

we know that
y+x=33-----> equation 1
3y-x/2=36----> multiply by 2----> 6y-x=72----> equation 2
adds equation 1 and equation 2

y+x=33
6y-x=72
-------------+
7y=105--------> y=15
x=33-y----> x=33-15----> x=18

the answer is
Susan's age is 18
Steven's age is 15
