Answer:
Step-by-step explanation:
Apply formula for the circumference of a circle.
The diameter 
is 13.8 cm.
By definition, the word "cardinality" is a term most especially used to determine the "measure of number elements in a set." In addition to that, a sample space simply defines the number of possible outcomes in a random experiment. Therefore, the answer would be "<span>Cardinality refers to the number of outcomes in a sample space."</span>
Length=2x
width=x
Perimeter of a rectangle=2(length) + 2(width)
We can suggest this equation:
24=2(2x)+2x
24=4x+2x
24=6x
x=24/6
x=4
length=2x=2(4)=8
width=x=4
area of a rectangle=length x width
area of this poster (rectangle)=(8 in)( 4 in)=32 in².
The area of this poster will be: 32 in²
1 gallon / 200 ft^2 = x gallons / 885ft^2
cross multiply (200 • x, 1 • 885)
200x = 885
x = 4.425 gallons
