Answer:
<em>First option: </em> 
Step-by-step explanation:
Given the point-slope equation 
, you need to solve for 
, because you are looking for the equation of the line in slope-intercept form:
Being 
the slope of that line, and 
the intersection of the line with the y-axis.
Then:
Apply Distributive property:
Subtract 7 from both sides:
Rewrite the equation:
(The linear function of the First option)
A = 103 degrees
You add all of them together to equal 180 and solve for x.
The center of the circle is the midpoint of the points or ((-4+6)/2,(-3+3)/2)=(1,0). Now, the diameter is the distance between the points. Using distance formulas (or noticing that the y-values are the same so it is a horizontal line), the distance is 10. Therefore, the radius is 5. The equation of a circle is (x-a)^2+(y-b)^2=r^2 where (a,b) is the center. Therefore, the equation is (x-1)^2+(y-0)^2=5^2.
Answer: The answer is 0.625 (the height of the cylinder is not needed!)
