Answer & Step-by-step explanation:
The circumference is basically the perimeter of a circle. The circumference of a circle is found by multiplying the diameter by π (pi):

or by multiplying the radius (which is half of the diameter) by 2 and π:

3 is the least common denominator . To find the least common denominator you list all the factors of both numbers and find the smallest one they both have in common beside one.
Answer:
C. Four less than seven times quantity of a number plus twelve.
Step-by-step explanation:
We can see from the given expression that 4 is subtracted from 7(x+12). The term used to describe subtraction is less. So, it is 4 less than 7(x+12).
We can clearly see that the first term is x and x can take any value.
So the whole expression will be four less than seven times quantity of a number plus twelve.
Hence option C is the correct answer ..
Since the line is parallel, the equation should have the same slope, therefore you know that y=4x+b.
In order to find b, you would need to plug in (-3,1) into x and y:
1=4(-3)+b
1=-12+b
b=13
Therefore the slope-intercept equation would be y=4x+13
