Find the area of the semicircle.Either enter an exact answer in terms of or use 3.14 for
and enter your answer as a decimal.

Answers
Answer:
14.13
Step-by-step explanation:
The formula for area of a circle is πr^2.
This is a semicircle which is half a circle, so the formula for area of a semicircle is (πr^2)/2
The diameter of the circle is 6, which means that the radius is 3. Since the radius of a circle is always half the diameter. (1/2*6=3)
This means we can plug the known values into our formula.
π(3)^2/2
Simplify.
9π/2
Now we plug 3.14 in for π.
9(3.14)/2
28.26/2
14.13
But for a semicircle the area is pi multiplied by radius squared divided by two
So, we do 3.14*3^2/2
Which is 14.13

Ranking the three from best to worst will be: point, line, plane. The justification is that, the starting concept determines the next one.
Step-by-step explanation:
The connection can be described by starting with the fundamental concept,procedure or strategy that give rise to the others. In this case, to form a line, you need to have points that join to extend infinitely in different directions. This means the point, is the fundamental concept, that will give the line.A plane is an infinite set of points that form a connected flat surface extending infinitely far in all direction. So here again, the plane exist where there is a set of points. However, a plane is named by three points that are in the plane but not in the same line. Hence, before naming a plane, the concept of a line should be considered. Ranking the three from best to worst will be: point, line, plane. The justification is that, the starting concept determines the next one.

Range of stuffed animals owned for the cluster is from 18 to 20.
What is scatter plot?
It is a graph that presents the relationship between two variables in a data-set.
What is cluster?
The data points in a scatter plot form distinct groups known as clusters.
Given a scatter plot
Range of stuffed animals is Y-axis.
Range of stuffed animals owned for the cluster
Cluster in the graph is between 18 to 20 on Y-axis.
Range is from 18 to 20.
Hence, range of stuffed animals owned for the cluster is from 18 to 20.

#SPJ2
To start, the range of a graph is its y values and in the case of this graph, the y values are the number of stuffed animals owned.
Now, look at the clustered area which consists of the points (7,19)(8,18)(8,20)(9,18)(9,19)(10,18)(10,20).
When you look at this cluster, notice that their y values all range from 18 to 20.
Therefore, your final answer would be that the range of the cluster is from 18 to 20.
Hope this helps and have a great day! :)

first find change
then find as a percent out of original
percent mean parts out of 100 so x%=x/100
find change first
25 to 50 is a change of 25
now we do
change/original=x%
change/original=x/100
25/25=x/100
1=x/100
x=100
answer is 100% change
25 points to 50 points is a 100% change
100% of 25 = 25
25 + 25 = 50
100% is your answer
hope this helps

we know that 6/8=3/4 because 3/4 times 2/2 (or 1) os 6/8
so we need the denomenators (bottom number) to be the same
so 5/6=10/12
1/4=3/12
2/3=8/12
add them together
10+3+8=21
21/12=1 and 9/12
subtract 1 and get
9/12 left or 3/4 yard left
B) leading most in the country to prosperity
C) causing a lasting boom in the timber industry.
D) causing massive starvation and a migration of people
Answers
Answer: Option 'D' is correct.
Step-by-step explanation:
Deforestation in Africa has had the effect of causing massive starvation and a migration of people as the number of population of nomads is more in Africa and they live in forests and get their food from there. As forest is the main source for them for their survival.
Deforestation means "Cutting down of trees in a large number ":
So, they get affected by this .
Hence, Option 'D' is correct.
