For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
According to the image, the line goes through the following points:
So, the slope is:
Thus, the equation is of the form:
We substitute a point and find "b":
Finally, the equation is:
Answer:
Answer:
C. 50.24 inches
Step-by-step explanation:
The area of a circle can be represented by . To find the circumference, all we need to do is know the radius, and then we can plug that value into the circumference formula
. So, to find the radius we see that:
So, the circumference is:
, which is closest to the answer C) 50.24 inches.
