Answer:

Step-by-step explanation:
The area of the circumference of a circle is:

We know that r is 8, so we can plug that into the formula.
However, there's a problem. We only want 3pi/4 of the circumference, not the entire circle's circumference. Therefore, we have to divide by part/whole. In this case, the part is 3pi/4, and the whole is 2pi (the entire circle is 2pi radians).

Answer:
Positive correlation
5 hours yield a score of 76
41 is the test score for no hours of study
Step-by-step explanation:
There is a positive correlation because the more hours spent on homework the better the test score generally it.
Use the function y=7x+41 by substituting x=5 and simplifying to predict the test score.
y=7(5)+41
y=35+41
y=76
The number 41 is the y-intercept and starting value. This means with 0 hours of study you are likely to score a 41 on the test.
