Answer:
<h3>
The cylinder's radius is <u> 2 </u> inches </h3><h3>
and it’s height is <u> 3 </u> inches.</h3>
Step-by-step explanation:
A diameter is two radiuses long, so the cylinder's radius is:
R = 4 in ÷ 2 = 2 in
The volume of cylinder is: V = πR²×H
Therefore:
12π = π×2²×H
12 = 4H
H = 3 in
Answer: the width should be 12 i might be wrong i might of overthinked it the question ;-;

Answer:
x=2andx= -2
Step-by-step explanation:
two x squared - 8 is equal to zero so you take the it across the equal to sign to get 2x squared equal to 8 you divide both sides divide both sides by two to give you two x squared is equal to 4 m taking root of Both Sides you get x equal to Plus or minus two so therefore x is equal to 2 or -2
Hey there :)
8P5 and 12C4
⁸P₅ = is 8! divided by ( 8 - 5 )!! is called the factorial You can see in the picture I have attached of how factorial is calculated

Let us do it separately:
8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 40320
3! = 3 x 2 x 1 = 6
Let us combine:

=
6720¹²C₄ is 12! divided by ( 4! times ( 12 - 4 )! )
=

Let us do it separately:
12! = 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 = 479001600
( 4! )( 8! ) = ( 4 x 3 x 2 x 1 )( 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 ) = 24 x 41320 = 967680
Let us combine:
= 495
