notice the volumes, the cone's volume is really one-third that of the cylinder, assuming "h"eight and "r"adius is the same on both.

Which correctly names a ray shown in a the figure???

$\\
\text{We know that a ray starts at one point and it continues out to infinity}.\\
\\
\text{and a line goes on to infinity in both directions, but a ray stops on one end.}\\
\\
\text{while a line segment is part of a line that has two endpoints.}\\
\\
\text{From the figure we can see that NH is a line segment as it has two endpoints.}\\
\\
\text{And LE, AP and EP are lines as they goes on to infinity in both directions.}\\
\\
\text{The Only ray is EC.}$
