Ineed knowing how to do the problem

Volume of a cone = pi * r² * (h/3)

If your diameter is 2, then take half of that for the radius; your radius is 1

Now plug in your given info:

V = pi * (1)² * (7/3)
= pi * 1 * (7/3)
= 7pi / 3

V ≈ 7.3304

Your answer is option D. 

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
