6. On a number line, point A has a coordinate of -6, and point B has a coordinate of 2. Which is the coordinate of point M, the midpoint of AB ? A) 0
B) -2
C) -3
D) 4

9514 1404 393

  B) -2

Step-by-step explanation:

The midpoint is the average of the end points.

  M = (A +B)/2

  M = (-6 +2)/2 = -4/2 = -2

The coordinate of M is -2.

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
