Since m is the midpoint of ab, then the following relationship is fulfilled:
 am =  \frac{ab}{2}
 Therefore, substituting values we have:
 2x+9 = \frac{8x-50}{2}
 From here, we clear the value of x.
 We have then:
 2x+9 = 4x-25
 9+25 = 4x-2x
 34 = 2x
 x =  \frac{34}{2}
 x = 17
 Then, the value of am, is given by substituting x in the expression:
 am=2x+9
 Substituting we have:
 am=2(17)+9
 am=34+9
 am=43
 Answer:
 
the length of am is:
 
am=43

Answer:

the volume of the cone would be approximately 490.09 m^3.

Step-by-step explanation:

The volume of a cone is pir^2h/3

So it would be pi*6^2*13/3

=pi*36*13/3

=pi*156

=490.09

Therefore, the volume of the cone would be approximately 490.09 m^3.

I hope this helped and have a good rest of your day!
