If the diameter is 12 inches, the radius is 6 inches, because the radius is half the diameter.
Given the formula

we have

When you fold the circle in half, the resulting figure has half the area.
So, you start with a circle with area 
You fold it once and you have a semicircle with area 
You fold it twice and you have a quarter circle with area

Answer:
P( B | A) will actually be the probability of the polygraph test being wrong.
Step-by-step explanation:
The event A represents the event that the subject is telling the truth.
The event B represents the event when he fails the polygraph test, which is indicative of the fact that he is lying.
The notation P( B | A) describes the probability that the subject fails the polygraph test given that he is actually telling the truth.
So in retrospect P( B | A) will actually be the probability of the polygraph test being wrong.
According to the question, there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants
<h3>Determining the area of a trapezium?</h3>
The trapezium is a 2 -dimensional plane shape with the area calculated as shown below:
The formula for calculating the area of a trapezoid is expressed as:
Area = 0.5(a + b)h
Given the following parameters
- a = 500 ft
b = 900ft
height h = 800ft
Substitute the given parameters
Area = 1/2 (500 + 900) * 800
Area = 1/2 (1400) * 800
Area = 560000 square feet
Since 1 acre is equivalent to 43560 square feet, hence the total acre required is expressed as:
Total acre = 560000/43560
Total acre = 12.856 acres
<h3>Convert the acres to total corn plant</h3>
Also since there are 37000 plants per hectare, the total corn plan required is 475,665.75 corn plants

Answer:
13.31
Step-by-step explanation:
First do 35.19-12.78=22.41
I assume slightly more than $9 is .1
then subtract 22.41-9.1=13.31
