Answer:
Given that the equation of a circle is :

I personally think its B but you gotta say if its either multiplication or addition or division
Answer:
The constant of proportionality in the equation y=0.41 is 0.41
Step-by-step explanation:
It is the fourth one because n could be any number on that red line because it’s is greater than -3
The answer to this depends on the angle at which they intersect. If it intersects<span> the cylinder perpendicular to the axis then a circle is formed. </span><span>If the plane intersects the cylinder at an angle, it will form an ellipse. This will be true until the plan is parallel with the axis of the cylinder. At that point, the surface will become a rectangle.</span>
