The graph would be a parabola with the vertex at point (0, 1)
The formula of a volume of a cylinder:

The formula of a volume of a cone:

Therefore, if a cone has the same radius and height like a cylinder, then the volume of a cone is three times smaller than the volume of a cylinder.
Therefore we have:

The formula of a volume of a sphere:

If a cone has that same lengths of a radius and a height, then the formula of a volume is:

If a cone and a sphere have the same radius, then the volume of a sphere is four times greater than a volume of a cone.
Therefore we have:

False. Parallel lines never intersect so therefore this would be false. Happy to help!
Answer: 130 degrees
Step-by-step explanation:
105+80+45+x=360
230+x=360
-230 both sides
X=130 degrees
