Answer:
Step-by-step explanation:
r = d/2
r = 4/2
r = 2
pi = 3.14
Circumference = 2 * pi * r
Circumference = 2 * 3.14 * 2
Circumference = 12.56
Area = pi r^2
Area = 3.14 * 2^2
Area = 4 * 3.14
Area = 12.56
D. 37.5% is the correct answer for your question
The most direct form to graph a line, is to find two points of it and connect them with a line.
Here we have:

Let's find the point where x = 0. To do this, we replace the x in the equation by 0:

We have our first point: (0, -6)
Next let's find the point where y = 0. Again, we replace y in by 0 in the equation:

We have our second point, (3, 0)
Now all we have to do is plot the points (0, -6) and (3, 0) in the plane, and connect them with a line, and then the line is graphed
The line should look like this:
2/10 in simplest form:
First, we can start out by finding the greatest common factor (GCF) of the numerator (2) and the denominator (10). This should always be done when simplifying a fraction the quickest way. Let's list out the factors of each number and find the common ones.
Factors of 2: 1, 2
Factors of 10: 1, 2, 5, 10
The GCF is 2, considering that 1 and 2 are the common factors, but 2 is the greatest.
Second, our last step is to divide
our numerator and denominator by the GCF (2) to find out our simplified fraction.

Answer in fraction form:

Answer in decimal form:
Everything should add up to 100%. So do
20 + 40 + 10 + 5 = 75
Now subtract 75 from 100
100 -75 = 25
25%
